The pneumatic actuator of giq-ab series pneumatic high vacuum butterfly valve is driven by compressed air. By changing the direction of the air path through the electromagnetic directional valve, pushing the mechanical transmission of the piston rack and gear, and driving the butterfly valve to do the opening and closing movement with the angular stroke output torque, the purpose of connecting or cutting off the air flow in the vacuum pipeline can be achieved. The valve plate of the valve adopts the clamping structure to clamp the sealing ring of the valve plate, which has the function of fine-tuning the main sealing. It is a new type of pneumatic high vacuum butterfly valve controlled by pneumatic actuator, which is divided into double acting and single acting (spring return) cylinders. Optional feedback signal device and electric valve positioner.

The applicable working medium is air and non corrosive gas.
