Pneumatic Actuator , Spring Return , Double Acting Pneumatic Valve Actuator

AT050 Electric Valve Actuator , AT Butterfly Valves Double Acting / Single Acting

1.single acting and double acting.
2.long service life.

3.high quality and reasonable price.

AT/GT series pneumatic actuators.DA and SR pneumatic actuators are design to work with Butterfly Valves and Ball Valves.

1. dual piston rack and pinion design of symmetric structures,rapid and smooth movement,high precision,high output power,by simply changing the position of the piston assembly against the direction of rotation available.
2. Extrusion of high-quality aluminum alloy cylinder block,by the precision machining of the inner hole and outer surface of hard anodized(anodic oxidation under special circumstances+ coating),longer life,low friction coefficient.
3. Integrated design,all the dual role and one role of the actuator models have the same cylinder and end caps,easily removed by installing a spring or spring to change the mode of action.
4. Combined pre-safe spring group,both in the assembiy process or use on-site in both convenient and safe to install or change the number of spring.
