MAINTENANCE (POPPET TYPE SOLENOID) - REPLACING SOLENOID
Caution: following ANY valve maintenance it is required to fully test valve operation and to complete FPS valve
automated valve repair check sheet FP081.0.
Note: for replacement of Parker spool-type solenoids with ASCO poppet type solenoids, refer to FPS instruction
bulletin 9640-1106.
Procedure shows an explosion proof limit switch (6010-1009), follow a similar procedure for the watertight model
(6010-1008).
Disassembly:
To remove the solenoid:
1)
Ensure valve is in its fail-safe (not actuated) position fully open or closed before disassembly. Pressure trapped
in the valve or actuator if partially stroked could be hazardous.
2)
De-pressurize process media and instrument air and turn off electrical power to the valve before attempting
any repair.
3)
Remove limit switch cover by loosening four capscrews.
4)
Disconnect the two power leads A from the limit switch terminal block (terminals 7 and 8) and the ground lead
B from the ground stud.
