Compact Rotary Air Actuators
Use rotary motion to drive devices in tight spaces. These small actuators are double acting, so they use air to exert force in both clockwise and counterclockwise directions.
Attach a sensor (sold separately) to activate relays and controllers.

Adjustable-Angle Rotary Air Actuators
Turn the adjustment bolt on these actuators to set the rotation you need for your application. Powered by compressed air, they create rotary movement. They’re great for moving and positioning in pick-and-place operations and for controlling flow in a system by opening and closing a valve. These actuators are double acting, so they use air to exert force in both clockwise and counterclockwise directions.
Attach a sensor (sold separately) to monitor position and activate relays and controllers.
304 stainless steel actuators withstand corrosive environments better than aluminum actuators. When you first set them up, attach a flow control valve to adjust the flow of compressed air.

High-Torque Rotary Air Actuators
Designed to turn heavy loads, these rotary air actuators have rack-and-pinion gears that provide high torque output. Actuators are double acting, so they use air to exert force in both clockwise and counterclockwise directions. You can change the shaft rotation by as much as 30° to meet the requirements of your application—turn the screw on the end cap to adjust.

Adjustable-Angle Compact Rotary Air Actuators
When you want to control the angle of your shaft’s rotation and are tight on space, choose these rotary air actuators. They’re our smallest rotary actuator, with only one internal moving part. Set the rotation angle you need by turning the adjustment bolts. Powered by compressed air, they rotate components in automated systems. They’re often used for moving and positioning in pick-and-place operations and for controlling flow in a system by opening and closing a valve. These actuators are double acting, so they use air to exert force in both clockwise and counterclockwise directions.

Universal Air Actuators for Flow-Control Valves
Attach these actuators to manual ball valves, butterfly valves, and plug valves with an ISO 5211 hole pattern to automatically start and stop flow with compressed air.
You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included). Use valve stem adapters to mount actuators to smaller ISO 5211 valve stems.
Single-acting actuators only require air pressure when actuated; they automatically spring closed when the air turns off.
Double-acting actuators require air pressure to open and close.
Pilot valves control the air to the actuator.
Limit switches change the position of the visual dome indicator and send an electrical signal to trigger alarms or other equipment when the actuator opens or closes the valve. The indicator displays green when the valve is open and red when the valve is closed. Switches attach to the top of the actuator with the included mounting bracket. All meet NEMA 4X for protection from washdowns, splashing water, corrosive liquid, and dust.

Air Actuators for Flow-Control Valves
These actuators are original manufacturer replacements for Duravalve and RuB valves.
You must control the air to the actuator using either an electric pilot valve (not included) or a manual on/off valve (not included).
Single-acting actuators only require air pressure when actuated; they automatically spring closed when the air turns off.
Double-acting actuators require air pressure to open and close.
