Selection of pneumatic valve actuator

Before selecting a pneumatic valve actuator, please confirm the valve torque. And increase the safety value in torque, with water vapor or non lubricating liquid media increasing the safety value by 25%; Non lubricating slurry liquid medium increases the safety value by 30%.
When selecting a valve torque of 210NM, a gas source pressure of only 5bar, and a non lubricating steam medium, considering safety factors, increase the safety value by 25% to 262NM. Use the double acting output torque table to find the corresponding torque value when the gas source pressure is 5bar. 277NM, model POADA300, should be selected.
