A Scotch yoke air piston actuator is a valve-switching device that converts compressed air energy into rotary mechanical motion to achieve valve opening and closing. It is commonly referred to as a Scotch yoke pneumatic actuator. Bigtork® Scotch yoke air actuators are well-suited for 90-degree rotary valves, such as ball valves, butterfly valves, plug valves, and others, enabling efficient valve operation. These actuators feature a modular design, comprising components like the body module, cylinder module, spring carriage module, among others, which facilitate easy on-site maintenance and storage.
Modular Design and Components of the BG Series Scotch Yoke Pneumatic Actuator
Body
The body is made of highlu rigid material in an integrative molding way.
Cylinder
Cylinder are processed with three precision grinding and hard chrome plated treatments, featuring exacting durability against wear and corrosion, as well as low friction coefficient. Seals offer minimun roughness possible to ensure the high.
Spring Cartridge
Piston
The piston feature excellent performance of dynamic sealing by the design with seals and durable ring of double orientation construction.
Springs
Springs are inspected by a rigorous incoming quality control system to ensure optimum perfarmance. The surface of spring is treated with anti-corrosion coating.
Hydraulic Manual Override
Enbedded screw manual and hydraulic manual design, reduce the product length to make installation convenient.
Modular Configuration
Modular design allows for effective selection and sizing of actuators, available for online maintenance of multi-functional modules. The BG series has interchangeable functional modules such as cylinders module, spring module, manual control, etc. Users can choose various suitable module types according to the process control flow needs of the valve.
