A compact Scotch yoke pneumatic actuator is a device that converts pneumatic energy into rotational motion using the Scotch yoke mechanism. It operates by utilizing a yoke connected to the actuator's piston, which moves in a linear motion. As the piston moves, it drives the yoke, which converts the linear motion into rotational motion. This rotational motion is then used to control valves or other devices in various applications. The compact design of the actuator makes it suitable for installations with limited space, while providing high torque output and precise control. Compact Scotch yoke actuators are commonly used in valve automation systems, where they offer reliable and efficient operation for controlling flow in industrial processes.
