This catalog describes a complete line of equipment available from RegO® for use with Liquid Propane (LP)-
Gas and anhydrous ammonia (NH3). The following points are important to know for proper use of the catalog:

1. Illustrations and drawings of individual products are representative of “product groups” and all products
within a product group are similar in construction.

2. Materials used for construction of products in this catalog are suitable for rated service pressure at
temperatures of -40°F to +165°F, unless otherwise specified.

3. Products in this catalog are only intended for use in LP-Gas and/or anhydrous ammonia service as follows.

a.“A” or “AA” prefix — Products with this prefix are suitable for NH3 service (i.e., contain no
brass parts).

b.“AA” prefix on relief valves — These valves are NOT suitable for use with LP-Gas service.
These are of partial aluminum materials and are listed by Underwriters Laboratories (UL)
for NH3 service only.

c.All other products including “A” prefix are suitable for use with LP-Gas & NH3 service.

d.SS” prefix—Hydrostatic relief valve with this prefix are suitable for NH3 and LP-Gas service
(i.e., they have stainless steel materials).

4. We manufacture valves and adapters designed to be used on LP-Gas and Anhydrous Ammonia systems,

Safety Warnings

Purpose
In its continuing quest for safety, RegO publishes a series of bulletins explaining the hazards associated with
the use, misuse, and aging of LP-Gas valves and regulators. It is hoped that these factual bulletins will make
clear to LP-Gas dealer managers and service personnel, that the utmost care and attention must be used in
the installation, inspection, and maintenance of these products, or problems could occur which would result in
injuries and property damage.

The National Fire Protection Association NFPA 58 Liquefied Petroleum Gas Code - 2020 Edition states in
Section 4.4 Qualification of Personnel; ”Persons whose duties fall within the scope of this code shall be
provided with training that is consistent with the scope of their job activities and that includes proper handling
and emergency response procedures... Refresher training shall be provided at least every 3 years, initial and
subsequent training shall be documented”. These “RegO Safety Warnings” may be useful in training new
employees and reminding older employees of hazards that can occur. It is recommended that all employees
complete the Propane Education Research Council’s Certified Employee Training Program.

This material can come from system piping between the container shut-
off valve and the regulator. Chips created during piping installation or
dirty piping can create this hazard. Corrosion inside of copper pigtails
and piping can cause problems. This can occur particularly when
LP-Gas contains high sulphur or excessive moisture.
Action Required: Make sure regulator inlet piping is clean at the
time of installation. Periodic checks should be made to ensure piping
remains clean without corrosion. Never use old pigtails on new LP-Gas
installations. Old pigtails can also work harden and crack if they have
been bent and twisted several times.

the regulator should be inspected at least once a year. If any corrosion is evident, replace the regulator.
2. Bad piping connections at the regulator inlet and outlet. This can
occur at the time of installation where connections are loose or the
regulator may have been overstressed by excessive wrenching. It
is important that proper wrenches, both on the piping and on the
regulator inlet and outlet, be used when connecting the system piping,
and that the regulator die cast body is not cracked by wrenching the
pipe too deeply into the body.
Action Required: Always test for leaks at time of installation and
inspect for leaks if there is reason to believe that pipe connections
could cause a hazard.

It is essential that the regulator bonnet cap be tightly in place at
all times to prevent the entrance of water, bugs, dirt, etc. Foreign
material can cause the regulator to function improperly with potentially
hazardous results.
5. Liquid propane in the regulator:
This can occur on recreational vehicles, unless the regulator is
installed substantially higher than the container shut-off valve. Here,
sloshing propane could get into the regulator with the resulting high
pressure downstream of the regulator. It could also occur on stationary
installations if the regulator is installed below the shut-off valve and the
container is over-filled.

Safety Warnings

Loss of Pressure Underground Installations

Freeze-up inside the regulator. Special hazards can occur if regulators are not properly installed in
underground systems. Water, dirt, mud and insects can get into the
regulator if the bonnet cap is not tightly in place and the vent is not
protected with a proper vent tube, opening above any potential water
level.
Most problems occur because the waterproof dome on the buried
storage tank does not extend above the ground level sufficiently to
keep out water and mud.
Ice Refer to NPGA No. 401.

This will prevent the regulator from regulating properly.

Regulator freeze-ups occur because there is excessive moisture
in the gas. Freeze-ups can also occur in pigtails that are kinked or
bent where free flow of the LP-Gas is restricted. These freeze-ups 18

 Pipe and Tubing Selection Guide

Use the following simple method to ensure the selection of the correct sizes of piping and tubing for LP-Gas vapor systems. Piping between the first and second stage
is considered, as well as lower pressure (2 PSIG) piping between the 2 PSIG second stage or integral twin stage regulator and the line pressure regulator; and low
pressure (inches of water column) piping between second stage, single stage, or integral twin stage regulators and appliances. The information supplied below is
from NFPA 54 2021 (National Fuel Gas Code) Chapter 6 and Annex B, and NFPA 58 2020 (Liquefied Petroleum Gas Code) Chapter 16; it can also be found in CETP
(Certified Employee Training Program) published by the Propane Education and Research Council “Selecting Piping and Tubing” module 4.1.8. These illustrations are for
demonstrative purposes, they are not intended for actual system design.

Instructions:
1. Determine the total gas demand for the system by adding up the BTU/hr input
from the appliance nameplates and adding demand as appropriate for future
appliances.
2. For second stage or integral twin stage piping:
A. Measure length of piping required from outlet of regulator to the appliance Length to Furthest Appliance
furthest away. No other length is necessary to do the sizing.
B. Make a simple sketch of the piping, as shown.
C. Determine the capacity to be handled by each section of piping. For
example, the capacity of the line between a and b must handle the total
demand of appliances A, B, and C; the capacity of the line from c to d must
handle only appliance B, etc.
D. Using Table 3 select proper size of tubing or pipe for each section of piping,
using values in BTU/hr for the length determined from step #2-A. If exact
length is not on chart, use next longer length. Do not use any other length
for this purpose! Simply select the size that shows at least as much capacity
as needed for each piping section.
3. For piping between first and second stage regulators
A. For a simple system with only one second stage regulator, merely measure
length of piping required between outlet of first stage regulator and inlet of
second stage regulator. Select piping or tubing required from Table 1.
B. For systems with multiple second stage regulators, measure length of piping
required to reach the second stage regulator that is furthest away. Make a
simple sketch, and size each leg of piping using Table 1, 2, or 3 using values
shown in column corresponding to the length as measured above, same as

 RegO Regulators Installation and Service Tips*

Why are the inlet nozzles reverse thread?

• Inlet nozzles are reverse threaded to allow for removal and service of
the seat disc and inlet nozzle, when debris has affected the regulators
performance. The seat disc and inlet nozzle can be cleaned and returned
back to normal service.

Regulator Installation Tips Inlet Nozzle

• Ensure your inlet nozzle is tightened securely into the body.

• Use back up wrenches when installing a new regulator to ensure the inlet nozzle
does not loosen.

• Install new pigtails when installing a new regulator.

• Do not use excess pipe sealant, as it can move downstream and affect regulator
performance.

• Install the regulator 12-18” off the ground and above snow accumulation.

• When regulators are not installed under a protective cover or tank lid.

• Install with the vent pointed vertically downwards.

Seat Disc
• If seasonal temperatures periodically reach -20 F, or colder the first stage
regulator should not be set higher than 10 PSIG.

• If seasonal temperatures periodically reach -35 F, or colder the first stage

regulator should not be set higher than 5 PSIG.

• Regulator must be vented 5 feet from relief discharge, any source of ignition, or
mechanical air intake, and 3 feet minimum from any building opening. A
• Regulator vent must be above highest probable water level on underground tank
installations.

• When installing regulators at a container connection, ensure the regulator is

placed above the container connection to ensure any liquid droplets fall back into
the container.

Regulator Service Tips

• Check regulator vents for obstructions.
Installed
• Make sure the vent screen and suppressor are properly in place. above highest

• Ensure your inlet nozzle is tightened securely into the body.
water level
• For high lock-up, or creep, check the inlet nozzle and seat disc for debris. Clean or
replace the inlet nozzle and seat disc, reinstall and recheck your lock-up.

• When available use Presto-Tap® gauges for leak checks to avoid any debris moving
from the regulators pigtail into the system.

• Make sure the regulator is properly selected for the BTU load and system demand.

Dielectric Second Stage Regulators
LV4403BD Series

Application
RegO’s Dielectric second stage regulators are designed to reduce
first stage pressure normally 10 PSIG (0.69 BARG) down to burner
pressure, normally 11” w.c. and are ideal for medium commercial
installations, multiple cylinders installations and normal domestic
loads.

RegO Dielectric second stage regulators are engineered to isolate

potential electrical current from metallic piping before entering a
building. The use of a separate dielectric union is not necessary
because the regulator contains a dielectric union as part of the inlet
assembly. Available in both SAE Flare and F.NPT inlet connection.

Features
• F. NPT Dielectric Union is made of Brass
• M. SAE Flare inlet connection made of solid Brass
• All second stage features are the same as LV4403B Series

 LP-Gas Cylinder and Service Valves

Safety Warnings Purpose

In its continuing quest for safety, RegO publishes a series of bulletins explaining the hazards associated with
the use, misuse, and aging of LP-Gas valves and regulators. It is hoped that these factual bulletins will make
clear to LP-Gas dealer managers and service personnel, that the utmost care and attention must be used in
the installation, inspection, and maintenance of these products, or problems could occur which would result in
injuries and property damage.

The National Fire Protection Association NFPA 58 Liquefied Petroleum Gas Code - 2020 Edition states in
Section 4.4 Qualification of Personnel; ”Persons whose duties fall within the scope of this code shall be
provided with training that is consistent with the scope of their job activities and that includes proper handling
and emergency response procedures... Refresher training shall be provided at least every 3 years, initial and
subsequent training shall be documented”. These “RegO Safety Warnings” may be useful in training new
employees and reminding older employees of hazards that can occur. It is recommended that all employees
complete the Propane Education Research Council’s Certified Employee Training Program.

These functions, although simple, are extremely critical in the safe

Important Factors:
Check cylinder valves for leaking components every time cylinders 1. Installation: It should not be necessary to remind the readers that

NFPA Pamphlet 58, and all other applicable codes and regulations.
Codes, regulations and manufacturers’ recommendations have

subject of cylinder valves and certainly does not cover all safety
practices that should be followed in installation, operation and codes, regulations and recommendations could result in hazardous
maintenance of LP-Gas systems which include cylinder valves. installations.

2. The bonnet and stem seal assembly of a cylinder valve are

extremely critical, since any malfunction could cause external leakage
and spillage. Check bonnet to see that it is in proper position. If there
is any doubt about tightness of threaded connection between bonnet
and body, valve must be repaired in accordance with manufacturers’
repair instructions before cylinder is filled. Handwheel must be in
good condition, stem threads must not be worn or damaged and
bonnet must be properly assembled. This area should be examined
each time the cylinder if filled. A leakage test should be conducted
while the shut-off valve is in the open position during filling.

3. The cylinder outlet connection is usually a female POL. Threads

must be free of dents, gouges and any indication of excessive wear.
Seating surface inside this connection must be smooth and free
of nicks and scratches to ensure a gas tight seal when connected
to a male POL cylinder adapter. Cylinder adapter must spin on
freely all the way, without indication of drag, roughness or excessive
looseness, and must then be tightened with a wrench. Connection
must be checked for leakage.

4. The pressure relief valve is of critical importance: Its proper

2. Liquid service shut-off (with excess flow valve)
3. Liquid filling
4. Pressure relief
5. Fixed liquid level gauge

LP-Gas Cylinder and Service Valves

Entire assembly must be free of dents, distortion or other indications

of damage. If relief valve appears too contaminated or damaged, the
cylinder valve must be replaced. (Caution: Eye protection must be
used when examining relief valves under pressure.)

5. The liquid service shut-off valve, with excess flow valve provided
on some cylinder valves, is also of critical importance. The excess
flow valve must be periodically tested for proper performance, in
addition to the inspection of the shut-off valve.

6. The fixed liquid level gauge on a cylinder valve is, when present,
essential to prevent overfilling the cylinder. The gauging valve must
operate freely, venting vapor when loosened, and sealing gas-tight
easily when tightened with the fingers. Gauge valves meant for
use with a socket key or screwdriver must also seal easily without
excessive torque. The fixed liquid level gauge diptube must be of
the proper length, and be in proper position. Periodic test should be
conducted by weighing the cylinder after filling, to determine that it
does not contain more than the allowable amount of LP-Gas. This At the very minimum, it is desirable that these customers:
check should be done periodically, and any time there is suspicion
that the gauge diptube may be damaged or broken. 1. Know the odor of LP-Gas and what to do in case they smell gas.
Use of the NPGA “Scratch ’n Sniff” leaflet could be productive.

2. Are instructed never to tamper with the system.

3. Know that when protective hoods are used to enclose regulators

and/or valves, that these hoods must be closed, but not locked.
Do Not Overfill Cylinders 4. Know the location of the cylinder shut-off valve in emergencies.

Do not fill a cylinder without first repairing or replacing the

cylinder valve, as required, if any defect is noted. B
While not required by codes, it is recommended that a plug or General Warning

 Thread Specifications

Because of the many thread forms available on equipment used in

Cylinder Valve Threads the LP-Gas industry today, the maze of letters, numbers and symbols
which make up various thread specifications becomes confusing. To
help eliminate some of this confusion, a brief explanation of some of
the more widely used thread specifications is shown below.

NGT and NPT Threads

Inlet Connections The NGT (National Gas Taper) thread is the commonly used valve-
to-cylinder connection. The male thread on the valve has about
two more threads at the large end than the NPT in order to provide
additional fresh threads if further tightening is necessary. Additionally,
the standard ¾” NGT valve inlet provides the greater tightness at the
bottom of the valve by making the valve threads slightly straighter
than the standard taper of ¾” per foot in NPT connections. In all other
respects NPT and NGT threads are similar.

 Service Valves for ASME and DOT Containers or Vapor Fuel Line Applications
D9101D/R, D9102D/R and DPT9102D/R Series

Application
Designed for vapor withdrawal service on ASME and DOT containers
or in fuel line applications. Since none of these valves have an
integral pressure relief valve, they may only be used as an accessory
valve on containers that have an independent pressure relief valve
sufficient for that container’s capacity. The Fixed liquid level gauge is
provided with a #72 low Emission fixed liquid level vent valve.

Features
• O-Ring stem seal design provides positive seal.

• Metal-to-metal back seat provides added protection against

leakage while the valve is open. DPT9102

• Valves with fixed liquid level gauges permit operator to quickly

determine when the maximum permitted filling level of the
container is reached.

• D9101R and D9102R Series with MultiBonnet® assembly allows

quick and easy repair of bonnet.

• DPT9102R Series With the service valve closed the pressure

test/Presto-Tap® port is isolated from the container. This
will allow a high pressure leak test to be conducted without
disconnecting the pigtail from the service valve. For more
information, see page C13 on this feature

Authorized Product Distributors. Know and understand NFPA Pamphlet 58 “Liquefied Petroleum Gas Code”, which is the law in many states.
This publication is available from NFPA, Batterymarch Park, Quincy, MA 02269. Following its requirements is
essential in the safe use of LP-Gas. Section 4.4 states: “Persons who transfer liquid LP-Gas, who are employed
to transport LP-Gas, or whose primary duties fall within the scope of this code shall be trained in proper
handling procedures. Refresher training shall be provided at least every three years and shall be documented.”
Make sure this valve is the proper one for this installation. Avoid misusing LP-Gas equipment.
Apply thread joint compound compatible with LP-Gas on valve external threads only. Make sure compound
never comes into contact with other parts of the valve.
Install valves by applying force to wrenching flats only.
Tighten pipe threads approximately 1 to 1½ turns beyond the hand-tight insertion point using a wrench which
avoids damage to other valve parts.
Check for damage and proper operation after valve installation. Check that the valve is clean and free of
foreign material.
Check container-valve connection with a non-corrosive leak detection solution before filling with LP-Gas.
Purge container before filling with LP-Gas (refer to the RegO LP-Gas Serviceman’s Manual for recommended
procedure).
Test excess flow check valve for proper operation before placing into service. See NPGA Bulletin 113 for
recommended procedure.
Check outlet connection make-up for leaks with a non-corrosive leak detection solution when placing
into service.
RegO Filler Valves: To prevent damage to the internal checks when it is necessary to utilize an unloading
adapter, use ONLY RegO 3119A, 3120 and 3121 Unloading Adapters with RegO Filler Valves. Carefully
follow the instructions supplied with these unloading adapters.
If container is not being placed into service at the present time, insert plug or cap onto the outlet connection.
In selecting a label for posting at the installation site, consider RegO part number 901-400 or 903-400 along
with your own, NPGA’s and others.
Remember to instruct the owner/user/customer in safety matters concerning LP-Gas and this equipment.
See RegO Safety Warnings “LP-Gas Cylinder Valves”, “LP-Gas Excess Flow Valves”, and “LP-Gas Filler
and Hose End Filling Valves” found in the cylinder valve, excess flow valve, and filler valve sections of the

Know and understand NFPA Pamphlet 58 “Liquefied Petroleum Gas Code”, which is the law in many states.
This publication is available from NFPA, Batterymarch Park, Quincy, MA 02269. Following its requirements is
essential in the safe use of LP-Gas. Section 4.4 states: “Persons who transfer liquid LP-Gas, who are employed
to transport LP-Gas, or whose primary duties fall within the scope of this code shall be trained in proper
handling procedures. Refresher training shall be provided at least every three years and shall be documented.”
Make sure this valve is the proper one for this installation. Avoid misusing LP-Gas equipment.
Apply thread joint compound compatible with LP-Gas on valve external threads only. Make sure compound
never comes into contact with other parts of the valve.
Install valves by applying force to wrenching flats only.
Tighten pipe threads approximately 1 to 1½ turns beyond the hand-tight insertion point using a wrench which
avoids damage to other valve parts.
Check for damage and proper operation after valve installation. Check that the valve is clean and free
of foreign material.
Check container-valve connection with a non-corrosive leak detection solution before filling with LP-Gas.
Purge container before filling with LP-Gas (refer to the RegO LP-Gas Serviceman’s Manual for recommended
procedure).
Test excess flow check valve for proper operation before placing into service. See NPGA Bulletin 113 for
recommended procedure.
Check outlet connection make-up for leaks with a non-corrosive leak detection solution when placing
into service.

Application
Designed especially for use as a primary relief valve on large
stationary storage containers, these low profile relief valves are
generally mounted in half couplings. However, they are designed
so that the inlet ports clear the bottom of a full 2” coupling. This
ensures that the relief valve should always be capable of maximum
flow under emergency conditions.

Features

10
• High capacity, low turbulence design has a maximum guiding REGO
area providing for dependable shut-off after opening.

• Built-in spring stop limits the rise of the seat in full open position
and prevents the spring from going “solid.” YEAR
WARRANTY
• External 3” NPT threaded body allows easy attachment of vent
stacks. Optional pipeaway adapter has break-off groove to
prevent damage to the relief valve should piping be stressed by
damaging winds.

break off groove that protects the valve from piping stress
damage.
3132-10
• Optional pipeaway adapters have grooves that will break off to
protect the relief valve from damage should excess stress be
applied to the piping.

• 3149 relief valves include weep hole deflectors, installed to guard

against flame impingement on adjacent containers.

• Most are ASME rated for use with LP-Gas and anhydrous
ammonia.

 Pressure Relief Valve with Check Device
RTG2831 Series *For Use Outside the United States

Application
These external valves are designed for use as a primary relief valve
on above ground domestic LPG DOT containers. The Check Device
(isolation valve) permits the exchange of the relief valve without the
necessity of evacuating the container.

Features & Benefits

• Relief valves provide “pop action” performance

• Weep hole is incorporated on the connection thread, which

indicates the check is closed and the valve may be removed.

• A metal to metal make up on the check device allows for a “signal

flow” of gas to act as a reminder that the container is unprotected
when the valve is removed.

• Complies with Standard CGA S-1.1 RTG2831V375

 DuoPort™ Pressure Relief Valve Manifolds for Small Storage Containers
8542 Series

Application
Designed especially for use as a primary relief device on smaller
stationary storage containers, with 2” NPT threaded couplings.
These manifolds allow servicing or replacement of either of the two
relief valves without evacuating the container or loss of service. The
operating lever selectively closes off the entrance port to the relief
valve being removed while the remaining valve provides protection

10
for the container and its contents. The rating of each manifold is
REGO
based on actual flow through the manifold and a single pressure relief
valve, taking friction loss into account. It is not merely the rating of the
relief valve alone.
YEAR
Features WARRANTY
• Allows for relief valve removal and replacement on a periodic
basis without shutting down and evacuating the container.

• Unique seat ring assemblies provide a smooth tubular section to

preclude turbulence and ensure more efficient flow capacity.

• Operating lever is only locked in the mid-position or in a position

to seal either relief valve. Placement of the clapper disc in an
intermediate position could restrict flow through one of the relief
valves, causing it to chatter and destroy the resilient seat disc.

• A rubber plug with chain is provided to protect manifold outlet

threads where the relief valve has been removed.

• “Pop-action” design insures maximum protection with only minimal

product loss at moderately excessive pressures.

• Resilient relief valve seat disc provides “bubble-tight” seal. 8542

D • Relief valves are ASME rated for use with LP-Gas and anhydrous
ammonia.

8545-500

The following warning information, Part Number 8545-500, is included Part

with each shipment of pressure relief valves and relief valve manifolds Number
to the first purchaser of the product from the factory. 8545-500 Adhesive Warning Label

This information is intended to be forwarded throughout the product

distribution chain. Additional copies are available from RegO and
Authorized Product Distributors.

DANGER READ THIS FIRST WARNING

LP-GAS IS EXTREMELY FLAMMABLE AND EXPLOSIVE
AVOID SERIOUS INJURY AND PROPERTY DAMAGE. IF YOU SEE, SMELL OR HEAR
ESCAPING GAS...EVACUATE AREA IMMEDIATELY! CALL YOUR LOCAL FIRE
DEPARTMENT! DO NOT ATTEMPT TO REPAIR. DO NOT STORE IN BUILDING OR
ENCLOSED AREA. DO NOT USE ON HOT AIR BALLOONS OR AIRCRAFT.
Make sure you are thoroughly trained before you attempt any pressure relief installation or maintenance.
Improper conditions or procedures can cause accidents resulting in property damage and personal injury.
Become thoroughly familiar with NPGA Safety Pamphlet 306 “LP-Gas Regulator and Valve Inspections &
Maintance” and RegO Safety Warning “Pressure Relief Valves” found in the relief valve section of the L-500
& L-102 Catalogs. Follow its recommendations.
Know and understand NFPA Pamphlet 58 “Liquefied Petroleum Gas Code”, which is the law in many states.
This publication is available from NFPA, Batterymarch Park, Quincy, MA 02269. Following its requirements is
essential in the safe use of LP-Gas. Section 4.4 states: “Persons who transfer liquid LP-Gas, who are employed
to transport LP-Gas, or whose primary duties fall within the scope of this code shall be trained in proper
handling procedures. Refresher training shall be provided at least every three years and shall be documented.”
Make sure this valve is the proper one for this installation. Avoid misusing LP-Gas equipment. Flow rates
in the charts are for bare relief valves found in the relief valve section of the L500 & L102 Catalogs. The
addition of deflectors, pipeaway adapters and piping will restrict the flow. To properly protect any container,
the total system flow must be sufficient to relieve pressure at the pressure setting of the relief valve in
accordance with all applicable codes.
Use only RegO adapters on RegO relief valves. Adapters not designed specifically for piping away RegO
relief valves, such as those with 90° turns or reduced internal diameters, will decrease flow dramatically.
These should never be used as they can cause the relief valve to chatter and eventually destroy itself.
Apply thread joint compound compatible with LP-Gas on valve external threads only. Make sure compound
never comes into contact with other parts of the valve.
Install valves by applying force to wrenching flats only.

Tighten pipe threads approximately 1 to 1½ turns beyond the hand-tight insertion point using a wrench which
avoids damage to other valve parts.
Check for damage after valve installation. Check that the pressure relief valve is clean and free of foreign
material. Make sure protective cap is properly in place.
Check that there are no leaks with a non-corrosive leak detection solution before filing with LP-Gas.
Purge container before filling with LP-Gas (refer to the RegO LP-Gas Serviceman’s Manual for recommended
procedure.)
In selecting a label for posting at the installation site, consider RegO part number 901-400 along with your
own, NPGA’s and others.
Remember to instruct the owner/user/customer in safety matters concerning LP-Gas and this equipment. See
RegO Safety Warning “Pressure Relief Valves” found in the relief valve section of the L-500 & L-102 Catalogs.

 LP-Gas Hose-End Filling Valves (With ACME Connectors)

Safety Warnings Purpose

In its continuing quest for safety, RegO publishes a series of bulletins explaining the hazards associated with the
use, misuse, and aging of LP-Gas valves and regulators. It is hoped that these factual bulletins will make clear to
LP-Gas dealer managers and service personnel, that the utmost care and attention must be used in the installation,
inspection, and maintenance of these products, or problems could occur which would result in injuries and property
damage.

The National Fire Protection Association NFPA 58 Liquefied Petroleum Gas Code - 2020 Edition states in Section
4.4 Qualification of Personnel; ”Persons whose duties fall within the scope of this code shall be provided with
training that is consistent with the scope of their job activities and that includes proper handling and emergency
response procedures. Refresher training shall be provided at least every 3 years, initial and subsequent training
shall be documented”. These “RegO Safety Warnings” may be useful in training new employees and reminding
older employees of hazards that can occur. It is recommended that all employees complete the Propane Education
Research Council’s Certified Employee Training Program.

Nature of Warnings
It is recognized that warnings should be as brief as possible, but
factors involved in filler valve and filling valves failure are not simple.
They need to be fully understood so that proper procedures and
maintenance can be used to prevent accidents. If there is a simple
warning, it would be:

Loosen filling valve from filler valve very slowly.

If there is a leak, know procedure to follow.

because the handle could snag on the ground and open the valve as
the hose is reeled back to the truck.

7554L Series valves feature a locking handle device to help prevent

accidental opening of the valve. It is ideal for all the same applications
as the 7554S Series and may be used on delivery trucks as it
incorporates the locking handle design.

Both valve series must be installed so that flow through the valve is
opposite to that of a conventional globe valve. This allows the inlet
flow to assist in closing the valve and prevents the valve from being
opened by high pump pressures.

Features 7554S
• Quick-acting design speeds transfer operations, permitting rapid,
one-handed opening and closing.

• Resilient seat disc provides positive shut-off.

• Flange seal stem design provides for leak-proof operation. No

packing to retighten or replace.

• 7554L Series incorporates locking handle to prevent accidental

opening of the valve.

• Vent valve installed on the downstream side of the valve permits

bleeding of trapped product to ensure safe uncoupling.

• Swivel seat disc minimizes grinding on the body seat and ensures
longer service life.

 Flange Seal Liquid Transfer Angle Valves for Bulk Storage Containers
7550 and 7551 Series

Application
Designed especially for liquid transfer of LP-Gas from consumer bulk
storage containers when used with a Chek-Lok® or equipped with
an integral excess flow valve. May also be used for vapor LP-Gas
service.

In NH3 applicator tanks they may be used as a vapor bleeder valve

or as a liquid withdrawal valve when installed in a coupling with a dip
pipe.

These liquid transfer valves are equipped with an integral excess

flow valve for liquid transfer directly from the tank fitting, or without an
integral excess flow for LP-Gas transfer through a Check-Lok® valve.

When equipped with an integral excess flow valve (7550PX), the

valve should be mounted in a forged steel 3000 lb. half coupling.
When mounted in a 1¼” x ¾” NPT reducing coupling, the ¾” female
thread in this coupling must be full length — equivalent to a forged
steel 3000 lb. half coupling.

The excess flow valve will not function properly if these specifications
are not met. Refer to the Warning Bulletin in the Excess Flow Valve
Section of this catalog.

 LP-Gas Excess Flow Valves

Safety Warnings Purpose

In its continuing quest for safety, RegO publishes a series of bulletins explaining the hazards associated with
the use, misuse, and aging of LP-Gas valves and regulators. It is hoped that these factual bulletins will make
clear to LP-Gas dealer managers and service personnel, that the utmost care and attention must be used in
the installation, inspection, and maintenance of these products, or problems could occur which would result in
injuries and property damage.

The National Fire Protection Association NFPA 58 Liquefied Petroleum Gas Code - 2020 Edition states in
Section 4.4 Qualification of Personnel; ”Persons whose duties fall within the scope of this code shall be
provided with training that is consistent with the scope of their job activities and that includes proper handling
and emergency response procedures... Refresher training shall be provided at least every 3 years, initial and
subsequent training shall be documented”. These “RegO Safety Warnings” may be useful in training new
employees and reminding older employees of hazards that can occur. It is recommended that all employees
complete the Propane Education Research Council’s Certified Employee Training Program.

simple. They need to be fully understood. If there is a simple warning,
it would be: Excess flow valves do not provide complete shut-off because there is

reduction in pipe size or number of other valves) decrease the
Selection and Installation flow rate to less than the valve’s closing flow.

F involves an analysis of the complete piping system and is beyond the
scope of this bulletin.

It is sufficient to say that an excess flow valve must be installed in

the correct direction and will close only if the flow of liquid or vapor
exceeds its designed closing rating. Many valves have been installed
with closing ratings considerably higher than any flow that could be
obtained by a downstream rupture in piping or hoses and thus give
none of the protection for which they are intended.

emergency shut-off valves with remote controls is recommended in
addition to excess flow valves.

Testing
The National Propane Gas Association Safety Bulletin #113-78
states:

“In order to test an excess flow valve in a piping system, the

flow through the valve must be made to exceed the valve’s
closing rating. This testing should only be attempted by trained

be obtained. The exact procedure used may vary with the
installation, advisability of gas discharge and availability of
equipment.

In general, most testing makes use of the fact that excess flow valves
are “surge sensitive” and will close quicker under a sudden flow surge
than under steady flow. A sufficient surge can often be created by
using a quick open/close valve to control sudden, momentary flow

and may be impractical, or illegal.

Any test of any excess flow valve will not prove that the valve will
close in an emergency situation, due to reasons cited before. This
test will only check the valve’s condition, and the flow rate sizing for
those test conditions.” F

of components made of materials such as metal and rubber.

The environment and conditions of use will determine the safe service
life of these products. Periodic testing at least once a year when tank
pressures are low and maintenance, as required, are essential.

Because RegO products have a long and proven record of quality

and service, LP-Gas dealers may forget the hazards that can occur
because an excess flow valve is used beyond its safe service life. Life
of an excess flow valve is determined by the environment in which
it “lives”. The LP-Gas dealer knows better than anyone what this
environment is.

NOTE: There is a developing trend in state legislation and

in proposed national legislation to make the owners of products
responsible for replacing products before they reach the end of their

Excess Flow Valves for Flange Mounting in Container Service
A3500 Series and A4500 Series

Application
Designed for mounting in flanged tank connections with internal
threads in the bottom of a container. They may be used in filling,
withdrawal or vapor equalizing application. They provide high flow
capacity with low pressure drop to minimize pump inlet line cavitation.

If a riser pipe to the vapor space is used with these excess flow
valves, the minimum inside diameter of the riser pipe must be at least
two times the valve thread size in order not to restrict flow to the side
inlet ports.

Flange mounted excess flow valves are readily accessible for

servicing and completely enclosed and protected in event of fire.
Because there is no direct connection between external piping and
the valve, stresses imposed on piping will not affect the excess flow
valve.

Flanged Installation In Container

NOTE: The opening in the tank flange should be machined with a
¼”-45° chamfer at the outer edge. The thread should be tapped
one or two turns large as checked by a plug gauge. This and the

10
undersize thread on the valve should permit the valve to be installed REGO
so that its outer face is at least flush with the outer edge of the flange.

The valve is screwed into this opening by fitting a ¼” flat metal piece
into the slot and turning until hand tight. A lubricant may be used, but YEAR
a luting compound is not necessary since this joint does not have to WARRANTY
be gas tight.

If any difficulty is experienced in “making up” the valve to fit flush, as

indicated, the thread in the tank flange can be tapped.

Design and construction of tank and flange must be in accordance

with the appropriate section of the ASME Pressure Vessel Code.

second wrench to secure the Chek-Lok in position.
2 Before beginning withdrawal, securely connect a RegO 7550P
angle valve or suitable shut-off valve to the adapter. Fully open
the shut-off valve – the valve’s handwheel must be fully opened
before connecting adapter to tank.
7590U-10 Adapter
3 Completely thread the adapter and shut-off valve assembly onto
the Chek-Lok by turning adapter’s coupling nut clockwise until it
is tight. Immediately close the shut-off valve. Listen for an audible
click to signal that the Chek-Lok has opened and is actuated for
liquid withdrawal. The flow can now be controlled by the transfer 7590U or 7591U Chek-Lok®
valve.
4 Check the coupling nut and adapter assembly for leaks using a
F suitable leak detection solution.
If the Chek-Lok fails to open after following this procedure, the
pressure downstream of the shut-off valve should be increased Connecting the 7572FC or

 Warnings

Purpose
In its continuing quest for safety, RegO publishes a series of bulletins explaining the hazards associated with
the use, misuse, and aging of LP-Gas valves and regulators. It is hoped that these factual bulletins will make
clear to LP-Gas dealer managers and service personnel, that the utmost care and attention must be used in
the installation, inspection, and maintenance of these products, or problems could occur which would result in
injuries and property damage.

The National Fire Protection Association NFPA 58 Liquefied Petroleum Gas Code - 2020 Edition states in
Section 4.4 Qualification of Personnel; ”Persons whose duties fall within the scope of this code shall be
provided with training that is consistent with the scope of their job activities and that includes proper handling
and emergency response procedures... Refresher training shall be provided at least every 3 years, initial and
subsequent training shall be documented”. These “RegO Safety Warnings” may be useful in training new
employees and reminding older employees of hazards that can occur. It is recommended that all employees
complete the Propane Education Research Council’s Certified Employee Training Program.’

protection for the system during transfer operations.
If the internal valve does not give 100% seal the valve should be
repaired immediately.
Spring Loaded Internal Valves

Spring loaded internal valves are manually opened by levers, by

means of fuse linked cable mechanisms or pneumatic or hydraulic
actuators. They incorporate an excess flow feature that will close the
valve when the flow through the valve exceeds its rate of flow. These
valves should never be locked open by means of wires, chains, pegs
or other devices.

Testing

Testing should be completed on a periodic basis.

1. To check operation of a spring loaded valve, activate the remote

control to close the valve while unit is pumping. If the meter indicator
flow continues, the valve should be repaired immediately.

2. Testing excess flow feature.

The National Propane Gas Association Safety Bulletin #113-78
states: “In order to test an excess flow valve in a piping system, the
flow through the valve must be made to exceed the valve’s closing
rating.’’

This testing should only be attempted by trained personnel

familiar with the process. If no one at the facility has experience in
proper testing, outside expert help should be obtained.

Pressure Differential Internal Valves (Flomatics®)

Pressure differential valves (Flomatics®) open by pump pressure and

close when the pump stops.These valves must never be locked open
by means of wires, chains, pegs or other devices.

Testing

Testing should be completed on a periodic basis.

1. To check operation of a differential pressure internal valve activate

the remote control shut-off valve while the unit is pumping. If the
meter indicates that flow continues the valve should be repaired
immediately.

2. Since the differential pressure internal valve requires at least 18

psi to open and 8 psi over container pressure to keep open, a test
may be performed to check for closure. With the PTO disengaged,
connect delivery hose to a container with very low pressure. Then
with hose end valve open, engage PTO. The internal valve should
remain closed, no flow should be detected through the meter. If
flow continues through the meter the valve should be repaired
immediately.

3. Tight Shut-Off — A test should be made to ensure the internal valve

will give a gas tight seal when the valve is in the closed position. First
ensure the pump prime valve is closed by turning clockwise until it
seats. Then with the valve closed (PTO disengaged) the product
downstream from the internal valve will have to be safely removed.
If the internal valve does not give 100% seal, the valve should be
repaired immediately.

General Warning
All RegO Products are mechanical devices that will eventually
become inoperative due to wear, contaminants, corrosion and aging G
of components made of materials such as metal and rubber.

The environment and conditions of use will determine the safe service
life of these products. Periodic testing at least once a year when tank
pressures are low and maintenance, as required, are essential.

Because RegO products have a long and proven record of quality

and service, LP-Gas dealers may forget the hazards that can occur
because an excess flow valve is used beyond its safe service life. Life
of an excess flow valve is determined by the environment in which
it “lives’’. The LP-Gas dealer knows better than anyone what this
environment is.

NOTE: There is a developing trend in state legislation and

in proposed national legislation to make the owners of products
responsible for replacing products before they reach the end of their
safe useful life. LP-Gas dealers should be aware of legislation which
could effect them.

Pneumatic Rotary Actuators
A3200OA Series

Application
These actuators provide the opening and closing of valves in
hard to reach or remote areas. Useful on bobtail delivery trucks,
transport trailers, and bulk plants, their remote control can safely
be piped to almost any location.

Features & Benefits

• For use with propane vapor, nitrogen or compressed air

• Compact size with same power and torque for easier placement.

• Low-friction construction with self-lubricated strips prevents the

actuator from sticking even after long periods of inactivity

• Double-acting movement powerful in both opening and closing

for true automated control.
A3217LOA
• Wear items, including pins, slots and bushings made of hardened
steel for the utmost durability and longevity.

• Scotch yoke design turns linear motion of piston into rotary

motion for valve actuation and eliminates rack and pinion, teeth
and gears that are susceptible to stripping, providing a lighter
weight, smaller product with longer life.

• Rolled cylinder provides a super smooth surface finish for less 10.11
wear and longer life.

• Expected service life 1,500,000+ cycles

Flomatic® Internal Valves for Bobtail Delivery Trucks, Transports and
Large Stationary Storage Tanks A7883FK

Application
Designed primarily for LP-Gas and anhydrous ammonia liquid
withdrawal on MC331 bobtail delivery trucks, transports and large
stationary storage containers with flanged connections. The valve is
fully automatic, opening and closing as the pump is turned on or off.

Features
Fully Automatic
• Operates on pressure differential from the pump to open and
close.
• Automatically closes should downstream line rupture causing loss
of pump differential pressure required to keep the valve open.
• Problems of improperly sized excess flow valves slugging shut
during liquid transfer are eliminated.

Faster Unloading
• Straight through flow design provides minimum pressure drop and
large flow capacity to the pump, resulting in higher flow rates and
greater pump efficiency.
• Unloading is quicker and turn-around faster to provide more
profitable operation.
A7883FK
Greater Protection
• Fully automatic operation virtually eliminates operator errors such
as forgetting to close the valve after product transfer.
• Fully internal design reduces possibility of spillage that may result
from a collision.
• Built-in visual indicator lets the operator know whether the valve
seat is in the open or closed position.
• Never a cable problem. These valves cannot be held open by wire
or any other means as the valve will not close as expected when
the pump is shut-off.
G
Less Maintenance
• Easily replaceable, high efficiency external filter removes
contaminants as small as 20 microns. Filter virtually eliminates
orifice clogging, excessive internal filter maintenance and service
downtime.
• No need to check or replace air lines, cables or cable connections.

Economical
• Completely equipped with mounting bolts, flange gaskets, quick
acting valve and filter - all in one purchase price.
• No need to purchase additional mounting equipment or actuating
accessories.
• Specify RegO Internal Valves on your next new tank body or when
your tank is rebuilt.

• Temperature range of -40°F to +165°F (-40°C to +73°C)

 Flomatic® Internal Valve Operation

General Information
RegO piston type Flomatic Internal Valves are normally closed and
use pressure differential to provide completely automatic service.
Mounted directly between the tank body and pump, the Flomatic®
uses the pressure differential developed by the pump to open the
valve and it closes automatically when the differential no longer
exists.

This means the RegO Flomatic opens when the pump is on and
closes when the pump is shut off – fully automatic.

3. Pump On – Valve Open

The force below the pilot stem forces the piston up to open the valve;
rotating the INDICATOR SLOT to its vertical (valve open) position.
Pump differential pressure in area D holds the PILOT STEM and
PISTON open. Approximately 20 psig pump differential pressure is
required to open the valve; approximately 8 psig differential pressure
1. Normally Closed will hold the valve open.
When the valve is closed, liquid flows into the INLET PORTS, through
a channel in the PISTON, and into area A. It also flows down through
the PRIMING CHANNEL in the valve body, into area B beneath the
valve seat, and into area C to prime the PUMP.

4. Pump Off – Valve Closes

With the pump shut off, the pressure in area D which holds the
2. Pump On – Valve Opening valve open, bleeds out through the #60 DRILL ORIFICE. This loss
When the pump is started, differential pressure transmits through the of pressure permits the SPRING to push the PILOT STEM down to
¼” piping into chamber D. lifting the PILOT STEM. This opens the reseat at point E. Since pressures are equal above and below the
seat between the stem and piston at E. Pump suction then evacuates PISTON, with no sustaining pressure in area D, the SPRING forces
the tank pressure in area A, which becomes equal to the pump the valve closed. The INDICATOR SLOT rotates to the horizontal
suction pressure. (valve closed) position.

On-The-Job Service Guide for the Flomatic® Valve

Introduction
Efficient, profitable transport and delivery truck operations depend on
keeping the equipment working safely and efficiently under changing
conditions. It is important to know how to eliminate expensive delays
by handling unloading problems as they arise.

The purpose of this technical guide is to provide basic information on

the Flomatic® valve, along with simple, appropriate steps to follow in
the event things go wrong.

The Flomatic® valve is mounted on the bottom of your transport or

delivery truck tank, with the pump mounted immediately downstream.
When the pump starts to push the liquid down the piping, the
Flomatic® Valve opens automatically, allowing you to unload the tank,
and closes when the pump stops pushing. It takes at least 20 pounds
per square inch of “push’’ at the pump to open the valve.

Your flanged Flomatic® valve has an indicating shaft on it that

shows whether it’s open or closed (Figure 1). If the indicating shaft is
horizontal, the valve is closed. If it’s vertical, the valve is open.

A threaded type, diaphragm-operated Flomatic® valve has an

indicating shaft on the bottom, covered by a clear plastic hood.
The indicating shaft projects down when the valve is closed and is
concealed when the valve is open (Figure 2).

Important Facts About Pressure

When handling propane or anhydrous ammonia, storage and
transport tank pressures vary from about 20 pounds per square inch
or less when it’s cold to 200 pounds per square inch or more in hot
weather (Figure 3). If you’re hauling butane, tank pressures will be 50
pounds per square inch or less.
G
The transport or delivery truck tank pressure may be higher than the
storage tank pressure when you are ready to unload (Figure 4). This
is because your rig may have been freshly loaded at the terminal or
bulk plant without a vapor equalizing line and hasn’t had time to get
back to normal. Also, the storage tank pressure tends to drop when a
lot of LP-Gas is being used.

Troubleshooting on the Job

O.K. So you follow your procedures, hook up your hoses, open the
required valves and start your pump. The indicating shaft on the
Flomatic® valve moves to the open position and the liquid goes in to
storage. Great! You’re happy and so is the boss, and so are we.

But, let’s say you do these things, start the pump and the liquid
doesn’t move. Now, how do you find out what is wrong?

For Transport Trailer Trucks Only (Figure 7a)

1. Check the difference between the pressure
in your transport and the storage tank. If there’s
15 or 20 pounds per square inch more pressure
in the transport tank than in the storage tank,
chances are the Flomatic® valve won’t open.
This is because the pump can’t develop enough
“push.’’

If you have a good bypass valve on your rig

to send the extra liquid back into the tank, you
can merely close the liquid shut-off valve in the
discharge line and restart your pump (Figure 8a).
Now, the Flomatic® indicating shaft should move
to the open position (see Figures 1 and 2).

2. Slowly open the liquid shut-off valve in the

discharge line and the liquid will start to move
out of the transport. If the Flomatic® valve
indicating shaft starts to move toward the closed
position once you’ve opened this liquid shut-off
valve all the way, throttle the valve for a while
until the transport tank pressure drops to where
the Flomatic® valve indicating shaft will stay
open. Then, open the liquid shut-off valve all the
Figure 7a. Unloading Diagram of Transport Trailer Truck way until you finish unloading.
The liquid flows out of the transport tank through the Flomatic® valve, into the pump and through the delivery hose to the storage tank. The vapor line
allows vapor to flow from storage back to the transport so that the storage tank pressure won’t build up too much and make the pump work harder
than necessary.

3. If your pump system doesn’t have a

bypass valve, the liquid shut-off valve in
the discharge line should be left partially
open when you restart the pump. Just be
sure that the pump is pushing at least 20
pounds per square inch, so the Flomatic®
valve can open.

Don’t worry about how much it may slow

case, the pump keeps the liquid moving at

For Delivery Trucks Only (Figure 7b)

1. Check the pump bypass piping. If

your truck is equipped with a manual
bypass valve, close it and try the pump G
again. (Figure 8b). If the Flomatic®
valve indicating shaft moves to the open
position, the problem is that the pump
can’t develop 20 pounds per square inch
or more to “push’’ open the Flomatic®
valve with the bypass valve open. You can
prevent this in the future by not opening
the manual bypass valve too wide.

USE EXTREME CARE AT ALL TIMES WHEN WORKING AROUND YOUR VEHICLE!
Watch out for drive shafts and moving parts. It is common knowledge that serious injury
can result if any part of one’s body or clothing is caught in moving machinery.

If you manually open the Flomatic® valve, you are responsible for safely unloading the
liquid and closing the valve when you’re through. If this procedure is being followed,
under no circumstances must the valve be left unattended. The valve must never be
permanently held in the open position.

If you are not able to cause the Flomatic® valve indicating shaft to
move to the open position after completing the preceding steps, a
complete detailed diagnosis will have to be made.

In the meantime, you can actuate the flanged Flomatic® valve by

using a special wrench and attempt to unload manually (Figure 9).

If you still can’t unload by following the preceding steps, it is

suggested that you unload by an alternate method, such as
through the valve normally used for liquid filling.

In any event, if you haven’t solved the problem and the unit still
doesn’t operate properly, immediately take it out of service, have a
complete analysis made and repair as needed.

 Filler Hose Adapters
3179B, 7577V and 7576

These adapters are designed with minimal flow restriction and

recommended for use on the outlet of the LP-Gas delivery truck filler
hose. If the controlled bleed off of the connection indicates the filler
valve on the tank being filled has failed to close, the hose adapter
should be left in place on the filler valve and disconnection should
3179A be made at the regular filler hose coupling. (Repair of the filler valve
must be made as soon as possible). An integral check valve in these
adapters helps prevent further loss of product. The standard filler
valve cap should be attached to these adapters when left on the
container.

1” Rotogage® Dial for Large Mobile and Stationary Containers
A9090 Series

Application
Rotogage® dials are designed to provide an accurate determination
of LP-Gas or anhydrous ammonia container contents. They mount in
a standard 1” NPT coupling on large mobile or stationary containers.

To operate the Rotogage® dials, the vent valve is opened and the
dip tube rotated slowly from the container vapor space to the liquid
space. The difference in appearance of the discharge indicates when
the liquid level is reached. Dial readings then indicate the percentage
of product in the container.

Features
• Supported design (TS Models) eliminates whipping and the need
for internal support hangers.

• Resistance-free nylon bearing inserts reduce friction and promote

operating ease.

• Dial face is dual calibrated to provide greater accuracy in reading

contents in containers which are not level.
Rotogage® Dial
• Interchangeable accessory dials permit interchangeable service
between LP-Gas and anhydrous ammonia.

 Pull-Away Valves for Transfer Operations
A2141 Series

Application
Designed especially to provide pull-away protection for LP-Gas and
anhydrous ammonia transfer operations including transport and
delivery truck loading and unloading, engine fuel container filling and
miscellaneous cylinder filling operations. When properly fastened to
the inlet end of the discharge hose, the valve is designed to stop gas
escape from both upstream and downstream lines in the event of a
pull-away. An excessive tension pull causes the valve to automatically
separate, closing two internal back pressure checks. Only a few cubic
centimeters of gas escape at the instant of separation.
A2141A6
It is recommended that a convenient means be provided to safely
remove the pressure from the line upstream of each coupling half to
enable reassembly of the valve. To reassemble, simply push the male
half firmly into the female half until the retaining balls slip into the
retaining groove. Check for leaks after reassembly.

NOTE: It is recommended that pull-away valves be maintained and

safety tested perodically to confirm that they will separate properly in
the event of a pull-away. Lubrication every six months is essential to
the pull-away’s operation. Dry nitrogen or other inert gas is suggested
as a source of pressure for pull-away tests.

If the A2141 pull-away valve is going to be stored for a period of time,

A2141 Series such as in seasonal applications, it is recommended
that it be sprayed with a good grade of rust-preventive machine oil, A2141A10
and covered to protect it from moisture.

Features
• Heavy-duty construction for long service life.
• A “true’’ pull-away type valve which simply reconnects by snapping

ESV Pneumatic Controls

Application
RegO Emergency Shut-Off Valves modified for remote pneumatic
shutdown operation retain all the operating features of the standard
valves.

Once equipped with pneumatic cylinders and then pressurized,

the pneumatic cylinder piston rod disengages from a striker plate,
allowing the ESV to be manually opened and the striker plate to act
as a latch and hold the valve open. Release of the control system
pressure for any reason closes the ESV for fail-safe operation.

Features
Convenience

• Closes the liquid and vapor ESV from a convenient remote

location. A6016 with 6016-60D Remote Close Actuator

• Independent closed loop system allows the ESV to be

pneumatically charged, but opened or closed manually or with
cable controls to conserve pressurized gas.

Reliability

• Independent closed loop system will continue to hold pressure

and close ESV in an emergency - even if supply pressure is cut
off.

Security

• Any loss of pressure from the control line, such as accidents or

the line melting from fire, automatically shuts down the liquid and
vapor ESV.

• ESV must be reset after automatic shutdown.

 Sight Flow Indicators for Bulk Plants
A7794 and A7796

Application
Designed to promote maximum pump efficiency, these indicators
enable bulk plant operators to visually inspect liquid flow conditions.
With glass on both sides of the indicator, flow can be observed from
either side, even under some poor light conditions. The integral swing
check also serves as a back-check valve to prevent reverse flow and
product loss if the hose fails in a loading operation.

By installing an indicator on the upstream side of the plant pump,

suction conditions can be observed and the pump speed adjusted to
obtain the maximum possible flow rate without cavitation. Additionally,
if an indicator is installed in the piping at the loading rack, just ahead
of the loading hose, the operator can maintain a constant check on
pump conditions.

Both installations are designed to allow for observation to provide

maximum pump efficiency and ensure safe plant pump operation.

In compressor operations a sight flow indicator installed in the liquid

line will give a visual indication when the tank car or transport is
emptied. Compressor operation can then be immediately reversed to
start recovery of the vapor.

A7794
Features
• Durable ductile iron body ensures long, trouble-free operation with
design working pressure of 400 PSIG.
• Glass is polished, ground and tempered after fabrication for

• O-ring glass seals provide for leak-tight operation.

 Hose End Adapter for Lift Truck Cylinder Filling
7193L-10A

Application
The 7193L-10A is designed to provide quick and easy attachment of
the filling hose to DOT cylinders equipped with RegO 7141M check
connectors.
95⁄8”
The 1¼” ACME outlet threads facilitate rapid make-up. When 13⁄8”
connected, back-checks in the adapter and check connector 11⁄4” ACME
automatically open. Low pressure drop between the two ensures high
filling rates. An integral check closes when disconnected, eliminating
the need to close any valves manually to disconnect the charging
hose.
⁄ ” NPT

Because a leak-tight seal is formed before the integral check opens or

closes, product loss is kept to an absolute minimum when connecting
or disconnecting the loading hose.

Combination Valve for Bulk Storage Containers
A2805C

Application
Designed for installation on bulk storage containers, this valve
combines a pressure gauge mounting and provision for a fixed tube
liquid level gauge.

The shut-off valve prevents the pressure gauge from being subjected
to constant pressure, thereby prolonging its life and accuracy. The
valve may be closed, and the vent valve opened to vent pressure
from the gauge to permit replacement.

For fixed liquid level gauging, the valve can be mounted at the
maximum permitted filling level. When equipped with a dip tube
threaded ⅛” M.NPT, it can be installed at any convenient level.

Features
• Temperature range of -40°F to +165°F (-40°C to +73°C)

Needle Valves 1224, 1316 and 1318

Application
These valves are high quality, “true’’ throttling valves. Unlike most
so-called needle valves, both the body seat and stem are tapered to
provide fine, precise control over a wide range of adjustment without
stem galling.

The 1224 may be used as a small, inexpensive shut-off valve

between a pressure gauge and bulk storage container to allow for
convenient gauge replacement.

The 1316 and 1318 provide taper pipe thread by left hand hose
connection threads and are useful in a wide range of torch and fuel J
burner applications where an accurate throttling action is required.
