Removal
WARNINGS
Lethal voltages are present in the actuator presenting a shock hazard
to personnel. Ensure the power supply to the actuator is isolated
before the cover is removed.
If an actuator is removed from a valve fitted in a live system, the valve
rotor may rotate uncontrollably in the body. An actuator must never
be removed from a valve installed in a live system.
The actuator case can be hotter than the ambient temperature. Care
must be taken when handling the actuator to prevent burn injuries to
personnel.
1 Switch off and isolate the actuator electrical supplies.
2 Manually operate the actuator to the low temperature position.
3 Remove the Terminal Box cover.
4 Label the wires to aid reassembly, disconnect from the Terminal Board
and pull the cables clear from the EMC Glands.
5 Note which valve port the cable entry glands are positioned over.
6 Remove the four bolts and spring washers (Fig 14 items 1 and 2)
securing the actuator mounting plate (Fig 14 item 8) to the valve. Where
the four screws are not accessible, such as on valve types 02GGH,
03GGS, 04GGH, 05GGS and 06GGS, the lower four bolts and spring
washers (Fig 14 items 3 and 4) should be removed.
