NOTE : All torques shown on the chart were derived from test data using water at 5C.
For torques using dry gases, multiply these numbers by 1.6.
Above table has additional 30% safety factor to average net torque.
For severe services, or unusual fluids or slurries, consult ST&H.
For 600 & 700 psig Torque, Please consult ST&H.

The torques listed are applicable to sea water, lubricating type of hydro carbons and most media at temperature 0~82 C (32~180 F).
The operating speed of the actuator must be considered in order to avoid water hammer when the valve is closed in junction
with Liquid.
