FNW 200A Installation, Operation & Maintenance Instructions

This instruction manual includes installation, operation and maintenance information for the figure 200A 2-piece
1000CWP, threaded end (NPT) ball valve.
WARNING
To avoid personal injury to your self, fellow workers, or damage to property from release of process fluid, before
installation:
a. Shut off all operating lines to the valve site
b. Isolate the valve site completely from the process
c. Release process pressure
d. Drain the process fluid from the valve site
1. Remove the protective plastic cap from the threaded ends and clean or flush the valve.
2. Before installing the valve, inspect the valve body port and associated equipment for any damage that may
have occurred and for any foreign matter that may have collected in shipping or storage. Make certain the
body interior is clean.
3. Before installing the valve, inspect the pipe line and mating pipe threads, making sure the pipe is free of
foreign material and the threads are clean and have no burrs or pits that could cause leakage.
4. Cycle the valve a couple of times before installation. Valves that are tested to MSS SP-110 may have water
trapped between the ball and body cavity. This can be removed by partially opening the valve, exposing the
cavity to the through port of the ball. Allow the water to drain out.
5. Use applicable sealant (e.g. - PTFE tape, high temperature pipe seal, etc.) to seal threaded ends on the
pipeline.
6. To prevent distortion or damage to the valve, do not apply torque through the valve. When tightening the
valve, always use a wrench on the end nearest the pipe being tightened. It is preferred that the pipe be
screwed into the valve, holding the valve stationary at the end being connected. Do not use the handle to
tighten the assembly as damage to the valve may occur.
7. Clean/flush the pipeline and leak test the system prior to using.
1. Ensure that the valve materials are compatible with the service and that the operating characteristics are
below the valve maximums.
2. Fluids containing particles or coagulating agents are not acceptable as they can reduce the life of the seats
and cause the torque to increase dramatically.
3. Care must be taken if throttling the valve (operation in partially open position). Critical pressure drops and
high flow rates can decrease the life of, or damage, the seats.
applications are recommended.
4. The valve comes standard with a locking device. Slide the locking plate up the lever before operating. Open
and close the valve by turning the handle one-quarter turn (90°).
