Air Power Actuator

A rack-and-pinion pneumatic actuator is a valve drive device that converts compressed air energy into rotational motion to open and close valves. The Bigtork® model is particularly suitable for 90° rotary valves such as ball valves, butterfly valves, and plug valves. Its modular design includes components such as the body, cylinder, and spring-loaded ferrule, facilitating on-site maintenance and storage.
