What is a pneumatic actuator?

A pneumatic actuator uses air pressure to create motion, which can be used to position a valve. The actuator consists of a piston placed inside a hollow cylinder, which when external pressure is applied, allows the movement of the piston through the creation of linear force.

Pneumatic actuators are the most common type of actuator used within process systems and provide a cost effective alternative for remote operation in surface applications.
