Torques for Sizing Actuators - Inch-Pounds (316 SS Seat) Actuator selection is dependent upon a number of variable factors such as pressure drop across the valve, seat and bearing friction torques, cryogenic temperatures and flowing media. The figures in the following table are based on standard valves and materials working in normal service conditions. A safety factor as recommended by the actuator manufacturer should be applied. Consult factory for cryogenic torque figures. Sizing & Selection Valve dia.
