Compact modern design with single and double acting units dimensionally identical.

All moving surfaces polished and with high quality bearings give low friction, long cycle life and no noise.

Lightweight high intensity die-cast aluminium pistons and end caps.

No lubrication required.

Option for IP67 switch box with 2 SPDT micro switches for open and closed position feed back and dome visual position indication.

Supplied fully function tested prior to shipping. (Push fittings + silencers used for bench testing can be removed to install Namur solenoid controller.)

When choosing our pneumatic actuator, we recommend the actuator torque is 30% higher than the valve it is being mounted onto.
