13. Actuator removal procedure
＜
Removal
＞
[Procedure]
1) Completely eliminate pressure in the pipe.
2) Turn off the power by left open or right open the valve.
3) Put the tip of the base plate removing jig at the center of the claw
on one side of the base plate. (Refer to
Fig. 13-1
.)
4) Move the removing jig in a way that it pushes the claw of the
base plate upward with the side of the valve as a fulcrum to
release the hooking with the main body of the valve.
(Refer to
Fig. 13-2
.)
5) For the other claw, perform the steps 3) to 4) to release the
hooking with the main body of the valve.
6) When the hooking of the both claws is released, lift the actuator
vertically to disconnect from the valve. (Refer to
Fig. 13-3
.)
＜
Attachment
＞
[Procedure]
1) Confirm that the opening display of the actuator and the
directions of the valve stem and shaft adapter are correct.
2) Check the fitting position of the top flange of the valve and the
base plate.
3) Push the base plate onto the valve until its claws firmly catch the
top flange while checking visually.
- When removing the actuator, be sure to use the "Base plate
removing jig". (Failure to so may cause, damage the Base
plate.)
- When removing the base plate from the valve, avoid applying
excessive force to a base plate removing jig to force the claw
to open. (It may cause the claw to be broken.)
- Avoid excessive repetition of attaching and removing the base
plate. (It may cause the claws of the base plate to have fatigue
fracture.)
- Has a metal joint (shaft adapter) between the valve and
actuator. Be careful of the shaft adapter's jumping out and fall
when removing the base plate from the valve.
- Be careful not to apply excessive load to the pipe and valve
when attaching and removing the base plate.
