Note:
1.Emerson Process Management 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
Valve Automation representative.
