Pneumatic Scotch Yoke Type Actuator Heavy Duty Highly Modular Design

Main Features

Scotch yoke actuators adopt a highly modular design concept and are divided into cylinder module (hydraulic cylinder module), box module and spring module to simplify field configuration. Users can flexibly choose the mode of action according to the actual use requirements, with strong mutuality and universality. It can easily realize the combination and replacement of single and double acting, manual operation and other modules without the need of special tools. Cylinder or hydraulic cylinder module can be configured on one side or on both sides.
The center body and yoke are made of ductile iron or cast steel, the yoke pin is made of alloy steel with excellent mechanical performance, and the adjustment bolts and fastening bolts of flange on both sides of the center body are of class 12.9 to ensure sufficient strength. The processing of the center body is one-step molding on four sides by high precision horizontal machining center for high transmission accuracy.
The transmission of the yoke pin is equipped with square copper slider structure, which ensures smooth transmission. The surface contact with the yoke can better protect the working face and extend the service life. The wear resistance and self-lubrication of aluminum bronze sliders can effectively improve the transmission efficiency.
Air connections are spread in the front and in the back symmetrically, convenient for installing attachment panels and connecting pipelines. Two air connections can meet clients' demands for motion speeds. A variety of air interfaces for pipe threads are available. The lifting rings are set according to the whole center of gravity, which is convenient for the lifting of the actuator. The rings are treated with dacrose anti-corrosion and lighting process.
