working principle

The compressed air is used to push the aluminum core piston in the pneumatic actuator to compress and drive the rotary head downward, so that the rotary head rotates 90° in the track of the aluminum core piston, and the pneumatic actuator and the disc plate are connected by the connecting square core to drive the disc plate. Turn the direction to open and close the valve.
