China Single Acting Scotch Yoke Pneumatic Actuator 2 PC Wcb Ball Valve

Double-acting pneumatic actuators and single-acting pneumatic actuators are actually the same in use. The most fundamental difference lies in the internal structure. Single-acting actuators have more springs, so the biggest advantage is that they can be reset after power failure! This advantage can close the valve through the return of the figure spring under dangerous conditions, reducing the risk factor!
