Actuator, Motor Operated Valve
-----------------------
Operation 0010 Actuator, Motor Operated Valve
1. OBTAIN WORK PERMIT.
2. CHECK EQUIPMENT TAG NUMBER AND NAME PLATE DATA.
3. WORK SAFELY, OBSERVE; PERMIT REGULATIONS, GOOD
WORK TECHNIQUES, BE AWARE OF HAZARDS.
4. CHECK OVER UNIT, PAY PARTICULAR ATTENTION TO;
LEAKING SEALS, GASKETS, GLANDS, DIFFERENTIAL GAUGES,
CLEAN INDICATING LIGHTS WITH OPERATOR CONCURRENCE.
5. CARRY OUT THE FOLLOWING CHECKS;
A) ENGAGE MANUAL CLUTCH.
B) OPERATE VALVE A FEW TURNS MANUALLY.
C) RETURN VALVE BY POWER.
D) ENSURE HAND CLUTCH DISENGAGES.
E) SELECTOR SWITCH FREE TO ROTATE TO ALL POSITIONS.
6. MOTOR, CHECK CONDITION AND SECURITY OF SERVICE AND
GROUND SIGNIFICANT CORROSION. NOTE ON THIS SHEET, ACT.
(EIM) BREATHER/VENT CLEANER DEVICE, TURN SEVERAL TURNS.
7. CHANGE OIL. FILL TO A LEVEL SUFFICIENT TO COVER THE
YOKE. DO NOT OVERFILL.
8. GREASE VALVE STEM.
9. FOR OTHER MOV'S, REMOVE PRESSURE RELIEF PLUG FROM
 STUFFING BOX.
10. INJECT SEALANT AMS 26-009-106 UNTIL AIR IN STUFFING
BOX IS ELIMINATED AND SEALANT COMES OUT.
11. REPLACE PLUG AND CONTINUE TO INJECT SEALANT UNTIL
INJECTOR PLUNGER HAS MODERATELY PRESSURIZED
SEALANT. OVER TIGHTENING OF INJECTOR WILL CAUSE
VALVE OPERATING TORQUES.
NOTE: ON VALVE WHICH HAS SEPARATE OPERATOR OR
GEARBOX: OPEN VALVE OPERATOR COVER AND CHECK
LUBRICATION CONDITION ON NUT DRIVE BEARING AND
WHEEL WORM GEARS. REMOVED HARDENED GREASE AND
RE-GREASE AS REQUIRED.
