2. If you are going to leave the bolt threaded into the cover, lock it with the jam nut (key 128) so that it cannot be
screwed into the cover and interfere with normal actuator operation.
To Lock the Actuator
1. Make sure the actuator diaphragm rod is retracted fully (the locked position of the valve). For a push‐down‐to‐close
valve and actuator, the valve will be fully open when locked. For a push‐down‐to‐open valve and actuator, the valve
will be fully closed when locked.
2. Make sure the jam nut (key 128) is loose. Then, screw the threaded bolt into the cover until it contacts the actuator
lever.
3. Rotate the threaded bolt until one of the holes in the locking disc (which is welded to the bolt) is in line with the
hole in the mounting plate (key 123). Tighten the jam nut against the cover.
4. Lock the plate and disc together with a padlock (not furnished by Emerson Automation Solutions).

not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
