Torque switches are factory set to actuator rated torque and should not be necessary
to reset. Call factory if you have special requirement. Torque switches set with
special tools to protect the actuator. If re-set without factory consultation warranty

6) Adaptation mounting for Actuator and valve
6.1 Drive Bushing
1) Removal
An internal actuator drive bushing is assembled on the bottom of the actuator with 4
retaining screws. Socket hex-key wrench is required for their removal.
2) Machining
The Drive bushing is machined to adapt to valve shaft ( or mounting coupler if
actuator is not direct mounted to the valve.) If key/keyway adaptation is used the
directionof keyway should align with one of the drive busing screws.
6.2 Reassembling the drive bushing
1) Check
the relative position of valve and actuator (Open-Closed).
If not rotate the actuator to same position as valve.
2) Line UP actuator
key way or other shaft configuration ( Square, etc.) with valve
Shaft or coupler Key Way, etc. ** Actuator can mount in one of 4 quadrants as determined by
the drive busing installed position.
3) Insert
the drive bushing back into the actuator with the 4 retaining screws.
