Instructions
SQM40/41…actuators rotation direction is not field reversible. Ensure that the
correct version is specified per application requirements. For example, a
clockwise-to-open butterfly valve requires a counterclockwise actuator (SQM40).
The SQM40 has a counterclockwise rotation when looking at the shaft.
The SQM41 has a clockwise rotation when looking at the shaft.
SQM40/41…actuators can be mounted in any orientation using the four M5
clearance holes at the corners of the actuator base. They can also be face
mounted using M5 self-tapping screws in the three holes around the shaft.
There are no restrictions regarding mounting orientation.
An optional base mounting bracket is also available (Part # AGA 57.5)
The actuator shaft can be disengaged by pressing the white shaft release button
down and forward. The button is located in the aluminum base to the right of the
terminal strips. Once the shaft is rotated to the desired position, simply push the
white button down and backwards so it releases, the shaft will now be reengaged.
