SELECTION GUIDANCE

Pneumatic actuator selection

Pneumatic actuators use compressed air to move a valve. For rack-and-pinion designs, piston movement drives a rotary output shaft. Selection depends on valve load and the air pressure available at the actuator.

Air supply and torque
Use the minimum available pressure at the actuator during movement. Ask for the output torque data for the selected arrangement, rather than choosing from the compressor pressure alone.
Loss-of-air response
Specify whether the valve should remain in position, open or close. Double-acting and spring-return arrangements behave differently; confirm the full actuator and control circuit.
Accessories and interface
Identify the need for a solenoid valve, position indication or positioner. Confirm air connections, mounting details, travel and the required opening and closing times.
Compare electric and pneumatic actuation

Ratings, options and dimensions depend on the selected configuration. Confirm the final datasheet before ordering.
