Pneumatic Actuator

ALIS Valves offers Pneumatic Actuators designed to automate the operation of industrial valves using compressed air. These actuators convert pneumatic energy into mechanical motion, enabling remote opening, closing or positioning of compatible valves. Quarter-turn pneumatic actuators are commonly used with ball valves, butterfly valves and plug valves, while other actuator designs are available for different motion requirements. Depending on the application, pneumatic actuators may feature rack-and-pinion or other suitable drive mechanisms, with double-acting or spring-return configurations to meet specific operating needs. Their compact construction, rapid response and compatibility with industrial automation equipment make them suitable for installations requiring reliable and efficient valve operation.

Pneumatic Actuators are commonly used in chemical processing, water treatment, oil and gas facilities, power generation, pharmaceutical manufacturing and general industrial automation. They can operate compatible valves in automated piping systems, helping reduce manual intervention and support consistent process control. Important selection factors include the valve’s required operating torque, actuator type, available air supply pressure, operating frequency, temperature range, mounting standard and environmental protection rating. Double-acting actuators use compressed air for both opening and closing, whereas spring-return actuators use air for one direction and a spring for the other, providing a defined fail position when correctly configured. Buyers should also consider compatibility with solenoid valves, limit switches, positioners and manual override accessories where required. Selecting and sizing the appropriate pneumatic actuator helps ensure dependable valve operation, effective automation and reliable performance within the specified operating conditions.
