Pneumatic valve actuator is an executive device that uses air pressure to open and close ball valve, butterfly or regulating valve. The pneumatic actuator powered by compresses air is easy to repair and maintain, and has good adaptability to the environment.
Tips: How to choose a pneumatic valve actuator?
Before choosing a pneumatic valve actuator, please confirm the valve torque. And increase 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.
