warehouses, meat processing plants, fisheries, dairies, breweries, supermarkets bottling companies and wineries all rely on
our valves and system solutions. The result is fresh food of the highest quality. But it goes beyond that: we control environ-
ments that have critical temperature needs. Our components control temperature in large buildings such as malls, pharma-
ceutical plants, institutions, hospitals and ice arenas. We keep industrial machinery cool so that it operates more efficiently.
Our components help farmers deliver fertilizer to their crops and keep produce fresh as it is transported from the fields. We
help prevent mines from flooding and keep the temperature and equipment cool for the workers.

How to use this catalog
This catalog is specific for ammonia refrigeration but other halocarbon refrigerant sizing tables are available, for other re-
frigerants, please use VSP2 selection software. The catalog is organized by product group. For most sections the first page
is an overview followed by product specifications, general information, application guide, selection tables to aid in selecting
a specific product and “How to order” tables. Additional information, in the appendices, provide schematic flow diagrams for
regulators, dimensional information on entire product line, valve torque specification and safety information.

Where cold ammonia liquid lines are used, it is necessary that certain precautions be taken to avoid damage that could result
from trapped liquid expansion.

Temperature increase in a valved off piping section completely full of liquid will cause high pressure due to the expanding
liquid which can possibly rupture a gasket, pipe or valve.

All hand valves isolating such sections should be marked, warning against accidental closing, and must not be closed
until all liquid is removed.

Check valves must never be installed upstream of solenoid valves, regulators with electric shut-off, nor should hand
valves upstream of solenoid valves or downstream of check valves be closed until all liquid ammonia has been removed.

It is advisable to install liquid relief devices suitable to safely and automatically bypass any trapped liquid ammonia
to the low side of the system. This method is preferred since it operates automatically and requires little attention.

Avoid all piping or control arrangements that might produce thermal or pressure shock. For the protection of people
and products, all refrigerant must be removed from the section to be worked on before a valve, strainer, or other device
is opened or removed. Flanges with ODS connections are not suitable for ammonia service.

VSP (Valve Selection program)

Parker’s Valve Selection Program helps you run calculations based on a set of operating conditions such as cooling capacity,
refrigerant, evaporation and condensation temperature. Then select the best components for your design.

The refrigeration software offers a simple, one stop shop in the system design process for all refrigeration projects.
One software for all your selection and calculation needs.
You can download the software here: https://discover.parker.com/VSP

Safety Practices
People doing any work on a refrigeration system must be qualified and completely familiar with the system and the Parker
valves involved or all other precautions will be meaningless. This includes reading and understanding pertinent Parker
product Bulletins and Safety Bulletin RSB prior to installation or servicing work.

PED
All valves in this catalog complies with Pressure Equipment Directive 2014/68/EU

Type: PA4C

Purpose
The PA4C weld-in line series inlet pressure regulators are designed to overcome
corrosion problems encountered in harsh environments. Being weld-in, the valves
reduce potential for connection leaks and can be entirely serviced from the top.
This improved design has a higher working pressure, greater working temperature
range and higher flow capacities than competitive products.
These valves provide long-term performance and with replaceable internal com-
ponents. Specially designed wear rings eliminate the need for removal of the body
from the line (maintenance-free).

Product Features
Stainless steel construction increases product life cycle
Cartridge based design simplifies service and eliminates body wear
Increased flow capacity enables smaller valve sizing
Overall weight reduction up to 50% compared to traditional flanged products
Integral features prevent contaminants from reaching the pilot section
of the valve
Suitable for ammonia, CO2 and halocarbon refrigerants
Multiple refrigerant capacities and configurations available
Interchangeable with other P-Series offerings

Electronic Valve New
Products

Type: PEV
Port Sizes: 20mm – 40mm (¾”– 1½”)

Purpose
The Parker Electronic Valve (PEV)provides a new level of control to industrial re-
frigeration. Managing liquid levels in vessels, superheat for direct expansion, brine
temperature in chillers and hot gas defrost are just few of many applications for
the PEV.
For basic liquid level control the PEV can be used directly with the HBLT-Wire level
probe without the need of a controller. For more advanced applications the PEV
is compatible with the HBLT-C1 controller or any other controller with a 4-20 mA
output signal.
The PEV weld-in valves are designed to overcome corrosion problems encountered
in harsh environments. Being weld-in, the valves reduce the potential for connec-
tion leaks and can be entirely serviced from the top.

Solenoid Valves New
Products

Type: PS4C

Purpose
The PS4C weld-in line series solenoid valves are designed to overcome corrosion
problems encountered in harsh environments. Being weld-in, the valves reduce the
potential for connection leaks and can be entirely serviced from the top.
This improved design has a higher working pressure, greater working temperature
range and higher flow capacities than competitive products.
These valves provide long-term performance and with replaceable internal com-
ponents. Specially designed wear rings eliminate the need for removal of the body
from the line (maintenance-free).

Product Features
Stainless steel construction increases product life cycle
Cartridge based design simplifies service and eliminates body wear
Increased flow capacity enables smaller valve sizing
Overall weight reduction up to 50% compared to traditional flanged products
Integral features prevent contaminants from reaching the pilot section
of the valve
Suitable for ammonia, CO2 and halocarbon refrigerants
Multiple refrigerant capacities available
Interchangeable with other P-Series offerings
Coil options to meet various applications

Capacities for R717 are based on 30°C liquid. Capacities are maximum and have no reserve for excess loads. Capacities apply to any A4A or A4W regulator
(or S4A and S4W) regardless of variation used.

Sub-cooled liquid: For each 5°C liquid is colder than base temperature, increase table valves 3% for R717.
1
0.034 bar pressure drop capacities apply only to regulators with LPD (low pressure drop) variation.
2
The 20mm regulator is available with throttling plug capacities equivalent to approximately 50% and 17% of the ratings in the tables.
3
The 32mm, 40mm, and 65mm - 100mm are available with throttling plug capacities equivalent to approximately 35% of the ratings in the tables.

Note: For liquid overfeed applications (nominal 2:1 to 5:1 ratio), add 20% to the evaporator load and select a regulator based on this increased load value.

For other refrigerants please use VSP2 Valve Selection Program.

Capacities for R410a and R507a are based on 40°C (100°F) liquid and 5°C (10°F) superheat entering the regulator. Capacities are maximum and have no
reserve for excess loads. Capacities apply to any A4A or A4W regulator (or S4A and S4W) regardless of variation used.

Sub-cooled liquid: For each 5°C/10°F liquid is colder than base temperature, increase table valves 4% for R410a and R507a.
1
0.034 bar (0.5 psig) pressure drop capacities apply only to regulators with LPD (low pressure drop) Variation.
2
20mm (3⁄4”) regulator is available with throttling plug capacities equivalent to approximately 50% and 17% of the ratings in the tables.
3
The 32mm (11⁄4”), 40mm (15⁄8”), and 65mm - 100mm (21⁄2” - 4”) are available with throttling plug capacities equivalent to approximately 35% of the
ratings in the tables.

Note: For liquid overfeed applications (nominal 2:1 to 5:1 ratio), add 20% to the evaporator load and select a regulator based on this increased load value

The design of the A2CK valve allows for higher flow and a “quick release” feature. However, it does not offer the same type of controlled response
which may be required for a standard regulator application. For those applications where a small regulator is needed for accurate upstream
pressure control, and A2A or A2B direct operated regulator should be considered.

Capacities for R717 are based on 30°C liquid. Capacities are maximum and have no reserve for excess loads.
Capacities apply to any A4A or A4W regulator (or S4A and S4W) regardless of variation used.

Sub-cooled liquid: For each 5°C/10°F liquid is colder than base temperature, increase table valves 3% for R717.

Note: For liquid overfeed applications (nominal 2:1 to 5:1 ratio), add 20% to the evaporator load and select a
regulator based on this increased load value.

For other refrigerants please use VSP2 Valve Selection Program.

All capacities are maximum for the conditions listed and have no reserve for excess loads.

1 R717 capacities are based on -7°C liquid with no flashing, -15°C evaporator temperature and no liquid overfeed. For liquid overfeed, multiply
evaporator KW by recirculating rate and size valve to the KW result. Use of -7°C liquid for capacities in this table is sufficiently accurate for most
liquid overfeed systems. To convert for 30°C input, multiply values in the table by 0.9.

2 R717 capacities are based on 30°C condensing temperature and the evaporator temperatures listed. See A4A suction capacities on page 10 for
other pressure drops and for corrections for liquid overfeed and sub-cooled liquid.

3 Hot gas heat reclaim capacities are in terms of heat of condensation rejected at the condenser and are based on saturated inlet conditions at
pressures equivalent to the condensing temperatures and for the pressure drops listed.

4 The 20mm port size S4A is available with capacities equal to 50% of the ratings shown.

5 CK-2 and S9A. See page 49 and 52 for low pressure drop at temperatures below -10°C.

For other refrigerants please use VSP2 selection software.

Gas Powered Valves
The CK-2 and CK-5, normally open, gas powered suction stop valves are uniquely
constructed to use discharge pressure to close. These valves are typically used for
low temperature applications in wet return lines on liquid recirculation systems or
on the liquid and gas return legs of flooded evaporators. Due to its normally open
construction, pressure drop is minimal in suction or wet return applications. In ad-
dition, normal gravity circulation is unrestricted on flooded evaporators. For gravity
flooded evaporators, both valves should be installed with their flow arrows pointing
towards the surge drum. Being pressure powered to close, this valve can overcome
sticking at low temperatures caused by the presence of viscous oil.
Unlike the CK-2, the CK-5 is designed to remain in a closed position in the event
that power to the pilot solenoid is inadvertently interrupted (i.e. a power failure),
during hot gas defrost. This prevents a “suction shock” condition under these cir-
cumstances.

Dual Position Control Valves
Designed to eliminate the damaging effects of hydraulic shock caused by liquid de-
celeration, vapor propelled liquid slugs, and condensation induced hydraulic shock,
the S4AD, CK-2D, and CK-6D combine the features of hot gas/soft gas valve con-
figurations and suction stop with equalization valve configurations. The S4AD can
additionally be used for high pressure liquid make up applications to prevent liquid
hammer, replacing parallel liquid line solenoid valves.
The CK-2D and CK-6D are low pressure drop, gas powered suction stop valves, for
low temperature ammonia, approved CFC, HCFC, or HFC refrigerants and corre-
sponding approved refrigerant oils or fluids. The CK-2D is a normally open valve,
which uses discharge gas to power the valve closed. The CK-6D incorporates a fail
safe feature, which holds the valve in the equalizing position until a safe coil pres-
sure is reached, should a power failure occur during the defrost cycle.
The valve position is controlled via the sequencing of two integral pilot solenoids
and can be held in a closed, partially open (approximately 10% of full flow) or fully
open position. By sequencing the solenoids based on time, users have the flexibility
to set each stage to meet their specific needs.

Use solenoid capacity tables on pages 53-57 for the S4AD valve and gas powered
capacity tables on pages 60-62 for the CK-2D and CK-6D valves.

In-Line Check Valves (CK-3)
The in-line CK-3 check valve prevents backward flow of high pressure refrigerant CK-3
gases and liquid. The PTFE valve seat and stainless steel body allows the CK-3 to
withstand corrosive environments associated in industrial refrigeration conditions.
The spring loaded check valve requires a minimum 0.34 bar (5 psi) pressure drop
to overcome the spring force and lift the valve seat, allowing the check valve to be
mounted in any position. The valve opens wide for flow in the arrow direction on
the body of the valve. When flow reversal occurs the CK-3 valve closes quickly and
reliably.

Strainers
The RSF/RSW refrigerant strainers collect foreign materials and dirt in a refrigerant system at minimal pressure drop in order
to minimize damage to or prevent malfunction of control valves. This, of course, is extremely important upon start-up of a new
refrigeration system where dirt, scale, and weld particles may be present in the system and are disturbed and circulated when
pressure testing or upon system start-up. Also when an existing system is revised, any settled dirt or foreign matter may be
disturbed and circulated throughout the system.
The fine stainless screen mesh will collect particles as small as 0.009” (0.23 mm) in diameter [60 mesh @ 0.0075” (0.19 mm)
wire]. Generous available screen area allows maximum dirt capacity at minimum pressure drop. The strainers may be close
coupled to Refrigerating Specialties valves having the same flange gasket size.

Notes:
Nominal capacities listed are based on normal defrost times saturated hot gas inlet to valve no less
than 30°C (86°F), a 5°C/10°F difference between evaporator, and an 8°C (47°F) defrost temperature.
These capacities can be adjusted depending on the evaporator type and mass, the thickness of frost
and other factors affecting the duration of the defrost process.

For other refrigerants please use VSP2 selection software.

Equalizing the coil pressure after a defrost is critical to ensure that large suction valves do not open
immediately and “shock” the system after the defrost has been terminated. This is especially true
on large, low temperature coils, where the difference between the defrost pressure and the house
suction is the greatest, and where the internal volume of the coil is largest. The addition of a vent
solenoid (usually piped in parallel to the automatic suction valve), which opens for a pre-determined
period after defrost (when the hot gas solenoid de-energizes, and the suction stop valve or suction
solenoid remains closed), slowly bleeds down the coil pressure. This effectively allows the defrost to
terminate in a “soft” and safe manner.

in their full open or full closed position.
The hand shut-off valves are available in both angle and
globe-Y body configurations and either standard or extended
bonnet versions. The extended bonnet allows for additional
insulation to be used.

Shut-off / Check Valve

Function and Design:

The shut-off / check valves are designed to provide two func-
tions: in the fully closed positions the valves will stop the flow
of refrigerant to allow for service or routine maintenance of
the refrigeration system; and in the full open position they
will provide a check function which will prevent the flow of
refrigerant in the reverse direction. These valves are meant to
be operated in their full open or full closed position.
The shut-off / check valves are available in both angle and
globe-Y body configurations and either standard or extended
bonnet versions. The extended bonnet allows for additional
insulation to be used.

Shut-off / Expansion Valve

Function and Design:

The shut-off / expansion valves are designed to modulate the
flow of refrigerant for liquid feed or expansion applications.
By varying the percent open the flow can be adjusted to suit
a variety of operating conditions. These valves also serve as
shut-off valves in the full closed position.

Rapid Purger (V300)
The Model V300 Rapid Purger is a unique energy-saving de-
vice designed to efficiently remove foreign non-condensable
gases from ammonia refrigeration systems.

Non-condensables like air, hydrogen, nitrogen, and hydro-

carbon gases reduce the overall capacity of the refrigera-
tion system. Higher pressures, which in turn causes longer
compressor runtime, longer condenser fan runtime, higher
compressor discharge temperatures, increase compressor
power costs, increase wear and tear on equipment, increase
leaks, reduce system efficiency, increase overall system en-
ergy costs are all consequences of non-condensables in the
refrigeration system.

In a refrigeration system non-condensables can be intro-

duced by:
• Inadequate system evacuation such as servicing compres-
sors, strainers, valves, start-up, etc.
• Refrigerant additions
• Leaks from valve stem packing, bonnet gasket, compressor
shaft seal, control transducers, etc.
• Separation of ammonia molecules (hydrogen and nitrogen) Product Features

Refrigerant Float Switch (LLSS)
The LLSS refrigerant float switch is a mechanical float device which indicates a particular
level of refrigerant in a vessel. It consists of a stainless steel welded chamber containing a fl
oat on the inside with a limit switch mounted on top. The chamber has a float-rod assembly
inside with a metallic attractor located on the upper end of the rod. As the level in the system
rises, the liquid fills the chamber causing the float ball to rise. The rising float with the attrac-
tor comes in close proximity of the magnet located inside the switch assembly. The magnet
is mounted on a lever that operates a snap action switch. The switch can turn an electrical
circuit on or off .
The float switch is used to open and close solenoid valves, to activate or de-activate electrical
controls, to energize or de-energize magnetic starters for starting and stopping refrigerant
liquid pumps and compressors, and as a safety device, to sound alarms and turn on lights
when there is high or low liquid level. The electrical switch and operating mechanism are
encapsulated within a UV resistant transparent housing.

Thermostatic Expansion Valves (TXV)
Ammonia Applications Only
Thermostatic expansion valves for ammonia applications
require special design considerations due to the erosive
effects of ammonia vapor. For this type of application,
Refrigerating Specialties has developed the types D and A
thermostatic expansion valves. Like other components of
ammonia systems, the types D and A valves are made from
steel and steel alloys.
With ammonia systems, the formation of flash vapor at
the expansion valve port causes valve seat erosion or wire
drawing to occur. This effect is further aggravated by high
velocity ammonia mixed with dirt or scale passing through
the port of the expansion valve. Fortunately, seat erosion can
be minimized and valve life extended if the following steps
are taken: Thermostatic Charges for Ammonia Valves
1. Maintain vapor-free liquid at the TXV inlet at all times Thermostatic charges C and L are available for the Type
2. Maintain clean ammonia through effective filtration D thermostatic expansion valve. The type L thermostatic

Suggested Flange Tightening Instructions for Manufacturer’s Instructions

Verify that piping into which a valve or flange is to be installed is properly supported and aligned. Be certain that the mating
surfaces of the gasketed joints are parallel, aligned and perpendicular to the pipe axis, in good condition and free of debris
and corrosion. Use only undamaged gaskets suitable for service in an ammonia refrigerating system.
Verify that all the nuts, bolts, cap screws and washers meet Parker’s requirements for the application and tighten
progressively in a diametrically staggered pattern. Leak test upon completing the installation.

4. Valve and Accessory Maintenance and Replacement Instructions

4.1. Maintenance: Parker Industrial Refrigerating Product service life may be significantly reduced without a continuing maintenance program.
The severity of the application, risk potential from a component failure, and experience with any known failures in the application or in similar
applications should determine the frequency of inspections and the servicing or replacement of our products so that they are replaced before any
failure occurs. A maintenance program must be established and followed by the user and, at minimum, must include instructions 4.2 through 4.6.
4.2. Installation and Service Instructions: Before attempting to service or replace any worn or damaged parts consult the appropriate Service Bulletin
or Operating Instruction for our product in question. You can download the operating instructions and datasheets under www.parker.com/refspec.
4.3. System Isolation Hazards: Care must be taken when isolating system components for service or replacement. As a guide see the appropriate
bulletins published by the International Institute of Ammonia Refrigeration available at www.iiar.org. Also see R/S Safety Bulletins RSBCV and
RSBHV available at www.parker.com/refspec for guidelines to avoid potentially dangerous conditions.
4.4. Visual Inspection: Any of the following conditions requires immediate system shut down, replacement of worn or damaged components, or
correction of any system malfunction. These conditions can mask potentially hazardous situations and should be corrected.
• Leakage to the atmosphere: Look and listen to see if there are any signs of damage to any of the components in the system.
• Damaged or degraded components: Look to see if there are any visible signs of wear, component degradation or excessive corrosion.
• Any observed improper system or component function.
• Excessive dirt and/or ice build-up.
4.5. Service or Replacement Intervals: It is the user’s responsibility to establish appropriate service and/or replacement intervals. Parker Industrial
Refrigerating Products do wear and can deteriorate over time. Environmental conditions can significantly accelerate this process.
Our products need to be serviced or replaced on routine intervals. Service intervals need to be established based on:
• Previous performance experiences.
• Government and/or industrial standards.
• When failures could result in unacceptable down time, equipment damage or personal injury risk.
4.6. Servicing or replacing any worn or damaged parts: To avoid unpredictable system behavior that can cause death, personal injury
and property damage:
• Follow all government, state and local safety and servicing practices prior to service including but not limited to all OSHA Lockout Tagout
procedures (OSHA Standard – 29 CFR, Part 1910.147, Appendix A, The Control of Hazardous Energy – Lockout / Tagout).
• Disconnect electrical supply (when necessary) before installation, servicing, or conversion.
• Components installed in pressurized refrigerant piping must be isolated from the refrigeration system and the refrigerant safely purged from the
component. See 4.3 above.
• Installation, servicing, and / or conversion of these products must be performed by knowledgeable and qualified personnel.
• After installation or servicing electrical supplies (when necessary) should be connected and the product tested for proper function and leakage.
If leakage is present or if the product does not operate properly, do not put the product or system into use.
• Warnings and specifications on the product should not be covered or painted over. If masking is not possible, contact your local representative
for replacement labels.
• Putting Serviced System Back into Operation: Follow the guidelines above and all relevant installation and maintenance instructions to insure
proper function of the system. You can download the operating instructions and datasheets under www.parker.com/refspec.
