Our newly-designed C Series Pneumatic Actuator is aluminum rack & pinion actuators in double acting and spring return based on our innovative and patented technology. This kind of actuator features a top mount multifunction indicator and open-close stop adjustment as a standard. In addition, state-ofthe-art engineering has allowed us to reduce the size of the actuator without losing any torque. The features and characteristics of the actuator have kept pace with 4th generation pneumatic actuator in the world.
