operational principle

Using compressed air to push the aluminum core piston inside the pneumatic actuator downward, the rotating head is driven to rotate 90 ° within the track of the aluminum core piston. The connecting square core connects the pneumatic actuator and the disc plate drives the direction of rotation of the disc plate to open and close the valve. When rotating, the metal pointer rotates with the connecting square core to the proximity switch position after opening, achieving feedback on opening or closing.
