If the actuator is to be replaced, remove the four studs B (if equipped) in the bottom of the actuator using the
appropriate hex key.
Assembly:
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.
1)
Ensure the same model of actuator is used in reassembly.
2)
If the solenoid used in the assembly is a NAMUR mount, screw in solenoid locator screw 4 to 5 turns. Ensure
that enough of the screw is protruding so that the mating hole in the solenoid adapter plate can locate properly.
3)
Follow assembly steps 3) to 6) in reverse for assembly.
CAUTION: IF VALVE IS A “NORMALLY CLOSED” VALVE, ENSURE THE BALL VALVE IS IN THE CLOSED POSITION
BEFORE RE-INSTALLING THE ACTUATOR. VALVE POSITION CAN BE CONFIRMED BY VISUALLY LOOKING AT THE BALL
POSITION TO ENSURE FLOW IS BLOCKED AND VISUALLY CONFIRMING THE LINE SCRIBED ON THE STEM IS
PERPENDICULAR TO FLOW
IF VALVE IS A “NORMALLY OPEN” VALVE, ENSURE THE BALL VALVE IS IN THE OPEN POSITION BEFORE RE-
INSTALLING THE ACTUATOR. VALVE POSITION CAN BE CONFIRMED BY VISUALLY LOOKING AT THE BALL POSITION
TO ENSURE FLOW IS NOT BLOCKED AND VISUALLY CONFIRMING THE LINE SCRIBED ON THE STEM IS PARALLEL TO
FLOW
4)
Place electrical service in operation and check valve for correct operation by means of visually verifying ball
position both energized and de-energized.
5)
Following actuator replacement, refer to section 7 for valve testing.
