Before choosing a pneumatic actuator, please confirm the valve torque. And increasing the safety value on the torque, water vapor or non-lubricating liquid medium increases the safety value by 25%; non-lubricating slurry liquid medium increases the safety value by 30%.
When the valve torque is 210NM, the air source pressure is only 5bar, and the medium is non-lubricated water vapor, considering the safety factor, increase the safety value by 25%, which is 262NM, and find the corresponding torque when the air source pressure is 5bar according to the double-acting output torque table. value. Should choose 277NM, the model is POADA300.
