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 Division representative.
