Installation
WARNING
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the actuator
where service conditions could exceed the limits given in this manual or on the appropriate nameplates. Use
pressure‐relieving devices as required by government or accepted industry codes and good engineering practices.
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
The M Series gear actuator is normally mounted on a valve at the factory. However, the actuator can be field mounted;
it can be mounted in any position on the A11 or A31A and it can be mounted in positions 1 and 3 on the A41, as shown
in figure 2. Make clearance considerations before mounting the actuator to determine the most suitable mounting
position.
The M Series actuator has a direct stab‐on design. Simply insert the valve shaft into the broached area of the body
housing. Then attach the mounting bracket to the actuator, using the torques listed in table 5, and attach the
mounting bracket to the valve.

1. Maximum recommended torque for the valve/actuator combination is based on valve shaft rating, actuator rating and rim force.
2. Rim force required to produce maximum recommended torque.
3. This column shows the number of times the handwheel must be turned to close the valve 90 degrees.
4. Shaft rating of the A11 valve.
