FieldQ Actuator Torque
Spring Return Actuators - lbf.in
Note:
1. Emerson recommends that the valve manufacturer supply the maximum required torque values (Including any adjustments or
suggested safety factors for valve service conditions or application).
Additionally, the valve manufacturer must identify at which position(s) and direction(s) of rotation (Counter Clock Wise or Clock
Wise) these maximum requirements occur.
2. If in doubt, or you require any assistance with sizing actuators, do not hesitate to contact your nearest Emerson’s
Actuation Technologies representative.
