OPERATION
The Valveworks USA Model FM1 gate valves are Ball Screw operated valves. The gate of the MODEL FM1
Valve is a one piece slab gate that uses two floating seats to generate a highly reliable seal. The slab gate
eliminates the chance of trapping pressure within the body cavity which can cause pressure locking.

Fully open the valve before installing or shipping. The sealing area of the gates, in the full open position, is
protected by the body and is less likely to be damaged.
Do not remove the molybdenum disulfide coating from internal parts. This coating serves as a lubricant and
corrosion inhibitor.
To hydrostatically test the valve body to full API test pressure, the valve must be in a partially open
position. When testing the valve in the closed position (seat test) do not exceed the working pressure
stamped on the valve identification plate.
During storage always leave the valve in the fully opened or fully closed position. This will tightly wedge
the gate against the seats and prevent damage to the sealing area of both the gate and seats.
Always remove the valve from service before work is performed on the stem bearings.
When lubricating the body do not exceed the maximum API working pressure stamped on the identification
plate.
The valve should be fully closed or fully opened during lubrication of the body or seats. Seat lubrication
pressures should not exceed the maximum allowable API test pressure.

This method of operation will prevent damage to the sealing surfaces of the gate and seats, and will increase the
life of the valve.

completely.

PERIODIC MAINTAINANCE
The Model FM1 gate valves are non-lubricated valves, in that they do not require the injection of lubricants or
sealants to effectively seal. However, to prevent corrosion and excessive wear a normal amount of lubrication is
recommended to extend the life and serviceability of the valve.
Maintenance Tools
To perform normal maintenance and lubrication, the following tools are recommended:

Grease pump with adapter and coupling

Safety pressure releasing tool

Valveworks USA API Gate Valves at 15,000 PSI W.P. are supplied with 9/16" 17-4SS autoclave fitting
connections.

BALL SCREW BEARING LUBRICATION

Valveworks USA FM1 valves are equipped with alemite hydraulic type 1/8" NPT bonnet grease fittings. Ball
Screw bearing lubrication is accomplished through this fitting using a standard type grease gun. Any good grade
No. 3 grease is recommended for this lubrication. Ball screw bearings normally do not require great amounts of
grease. If too much lubrication should occur, excess grease will flow around the stem to the atmosphere.

VALVEWORKS USA

Model FM1 Operation Manual

CAUTION: If bearings should need to be changed, the valve must be removed from service. During
pressurized valve body lubrication, pressure applied to the valve body with the grease gun must not exceed the
maximum working pressure of the valve being lubricated.

VENTING OR DRAINING A VALVE

Most products contain a certain amount of water, line scale, sediment and other foreign matter which tend to
accumulate in the valve body. A regular draining program will increase the life of a valve against damage
caused by:

Water freezing in the body cavity, causing damage to the body.

An accumulation of foreign matter in the lower part of the body, which could prevent the valve from fully
closing, resulting in a throttling action which may cause inefficient sealing.
Foreign matter trapped in the body may become lodged between the sealing surfaces of the gate and seats,
resulting in scored or damaged sealed.
Venting a Model FM1 valve is a positive method of checking the sealing ability of the gate and seats. If the
body vents down to zero pressure with the valve in fully closed position, this is definite indication that
sealing surfaces are in good condition.

PROCEDURE TO VENT OR DRAIN

Place the valve gate in a fully opened or fully closed position.

Remove the safety cap from either

body grease fitting

Attach the pressure release tool.

CAUTION: Remove the safety cap slowly to allow the ball check to sufficiently seal and avoid
uncontrolled venting. Should the ball check fail to seal properly, pressure will continue to blow through
the safety cap orifices. You should then retighten the safety cap screw and vent through the other body
grease fitting. Once the body pressure is bled to zero you should then attempt to repair the leaking ball
check.

Screw the stem of the releasing tool into the fitting forcing the ball check off its seat. The valve will vent
and drain once the ball check is unseated.

Model FM1 Operation Manual

A program of regular draining and body venting is the most positive way to prevent problems caused by foreign
matter in the valve. However, if a regular draining program cannot be followed, it is recommended that valves
be drained after the following operations:
After a well has come in and has been cleaned up.
After a mudding operation.
After a cementing operation.
Anytime the valve seems hard to operate by hand and will not fully open or close by the required number of
hand wheel turns.
When the valve is hard to operate from the fully open or fully closed position because it is "pressure locked"
or "Iced-up".
"Pressure locked" is a condition that may exist with any dual seat expanding type gate valve when body
pressure greatly exceeds line pressure. It occurs only in fully closed position and is a positive indication that
sealing surfaces are in good condition.
"Iced-up" is a condition caused by a restriction in the flow or a differential in the pressure of gas flow at high
pressure, which produces extremely low temperatures.
These restrictions or differentials in pressure may be caused by throttling through a valve, by leakage of a
closed valve or by Leakage through the stem packing. Valves in service on gas containing hydrates or in fresh
water service, exposed to low external temperatures may also "iced-up". In this case it is advisable to inject
alcohol or glycol into the valve body through the drain fitting to combat these conditions.
The same procedures are used for injecting alcohol or glycol as are used for valve body lubrication. Do not
operate the valve immediately after injecting as these fluids should be retained in the body to perform the
Antifreeze effect.

TEST PROCEDURE

Grease and insert a BX156 ring joint into one of

the body flanges. Note: Refer to the end of the
manual for studded outlet to prepare for testing.

Be sure that the test flange has a tightened grease

fitting, all of its studs, and a nut on each with all
of the nuts on the grease fitting side as shown.

Align the test flange studs with the body flange

holes. Then, push the test flanges, its studs, and
their hex nuts onto the body flange.

Screw the each hex nut on the vacant side of a

stud as shown until all of the studs have a nut on
the test flange and the valve flange.

Tighten the hex nuts on the test flange side

with an impact wrench until they are tight.

A finished flange should appear as shown.

NOTE: Repeat the above steps for the opposite flange.

Remove the grease fitting cap from one test flange

and attach a pressure release tool as shown above.

Remove the grease fitting cap from the opposite

test flange and attach the flow line as shown above.

Hydrostatic Body Test

With the pressure release tool and flow line connection tight, open the valve partially, and apply the test
pressure for at least three (3) minutes.

Bleed off the pressure until its reduced to

zero, and close the pressure release tool.
Raise the pressure back up to the test pressure for the secondary pressure-holding period of at least three (3)
minutes.
Bleed off the pressure until its reduced to zero. Then, close the pressure release tool and the valve.

The hydrostatic body test pressure shall be determined by the rated working pressure of the equipment.
Hydrostatic test pressures shall be as given as tabulated below.
