Disassembling the valve for cleaning or part replacement
— Disassembly Procedure B
A removable actuator makes piston-type valves easy to access for maintenance.
Should you need to clean the valve or replace a part, the actuator is removable follow-
ing these procedures:
1. Shut off the water at the master shut off valve.
2. Using a pair of adjustable pliers clamped in the area of the valve indicated in the
illustration (next page), unscrew the actuator counterclockwise.
3. To inspect the piston seals or replace the piston, gently pull piston from the bottom
to pull it out of valve.
4. To remove solenoid, hold gray flow ring and twist counter-clockwise to unscrew.
To reassemble the valve actuator assembly, screw it into the valve body in a clock-
wise direction until the actuator body contacts the valve body. Caution: Do no over
tighten as this may cause damage to the actuator. Do not use any pipe dope or tape
on the actuator threads. The bleed ports (holes) just above the threads can become
clogged and prevent operation.
Two types of Repair kits are available, the SRK-1 Solenoid Replacement Kit and the
PRK-100 Piston Replacement Kit.
