Pneumatic actuators are devices powered by compressed air. These devices are employed for the actuation of industrial valves. Pneumatic valve actuators are used in both isolation and control valve actuation. Based on the valve actuation mechanism, these actuators can be classified into linear, quarter-turn, and multi-turn pneumatic actuators. Pneumatic valve actuators are extensively used in downstream oil and gas facilities, power generation plants, and mining facilities, where clean air (less humid) is abundantly available for compression.
