The compressed air enters the cylinder and pushes the piston to move linearly. The piston through the piston pin and the fork U-shaped groove design converts the linear motion of the piston into the rotary motion of the york, and the rotation of the york drives the output shaft to rotate, thereby realizing the control of the valve.
