Pneumatic Actuator 82046L
Rev 5 – MAY 2019
OMMGGP00185
Removal
WARNINGS
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.
Ensure the valve and actuator are set to the low temperature position.
Isolate and disconnect the positioner pneumatic connections.
Note which valve port the pressure connections are positioned over.
Remove the four bolts and spring washers securing the actuator
mounting plate to the valve. Where the four screws are not accessible,
such as on valve types 02GGH, 03GGS, 03GGH, 04GGS, 04GGH, 05GGS
and 06GGS, the lower four bolts and spring washers holding the actuator
to the mounting plate should be removed.
WARNING
The actuator is heavy. The appropriate manual handling precautions
must be applied to prevent injury to personnel.
Note that when removing the actuator from valve types 02GGH, 03GGS,
03GGH, 04GGS, 04GGH and 06GGS, the mounting plate will remain in
position on the valve. At this stage the mounting plate on these valve
types can also be removed from the valve by removing the four
countersunk screws.
Installation
On valve types 02GGH, 03GGS, 03GGH, 04GGS, 04GGH, 05GGS and
06GGS, if the mounting plate has been removed, replace it using the four
countersunk screws tightened to the relevant torque setting detailed in
Table 2 page 31. For all other valve types, ensure that the mounting plate
is secured to the underside the actuator with the four bolts and spring
washers tightened to the relevant torque setting detailed in Table 2 page
31.
Ensure that the actuator is set to the low temperature position.
WARNING
The actuator is heavy. The appropriate manual handling precautions
must be applied to prevent injury to personnel.
Mount the actuator (complete with mounting plate where relevant) onto
the valve body, with the pressure connections positioned over the valve
port noted during removal. Secure to the valve using the four bolts and
washers to secure the mounting plate to the valve (or the actuator to the
mounting plate on valve types 02GGH, 03GGS, 03GGH, 04GGS, 04GGH,
05GGS and 06GGS).
