Scotch Yoke Heavy Duty Pneumatic Actuator

Scotch Yoke Heavy Duty Pneumatic Actuator

Scotch yoke pneumatic actuator from Zhejiang Jimai Auto-Tech Co,.Ltd is a advanced mechanical device that can convert liner force into operating torque. The rotation of the shift fork drives the output shaft to rotate, thus realizing the control of the valve. It is mainly used in quarter-turn applications, like butterfly valve, ball valve, plug valves, etc. Scotch yoke pneumatic actuator has the much more higher output torque under the same air pressure compared with rack and pinion actuator, which allows it be utilized in more advanced applications.
