Valve Installation Procedure
Position the connecting pipe fl anges in the line to insure proper
alignment prior to valve installation. Spread the pipe fl anges apart
enough to allow the valve body to be located between the fl anges
without actually contacting the fl ange surfaces. Exercise particular
care in handling the valve so as to prevent possible damage to the disc
or seat faces.
Note: Actuator must be mounted at or above pipe center line for all
actuator types. (Fig. 6)
1. For Lug style valves:
a. Place the valve between the fl anges.
b. Install all bolts between the valve and the mating fl anges.
Hand tighten bolts as necessary. (Fig. 7)
2. Before completing the tightening of any bolts, the valve should be
centered between the fl anges and then carefully opened and closed
to insure free, unobstructed disc movement.
3. Using the sequence, (Fig. 8) tighten the fl ange bolts evenly to assure
uniform compression. In assembling fl ange joints, the resilient
seating surface shall be uniformly compressed. (Fig. 5)
4. If an actuator is to be operated, electricity should be connected to
the unit in accordance with the local electrical codes.
5. Cycle the valve to the fully open position, then back to the fully
closed position, checking the actuator travel stop settings for proper
disc alignment. The valve should be operated to assure that no
binding is taking place. If no power is available, use the manual
handwheel.
6. The valve is now ready for operation.
