The pneumatic actuator of giq-b series pneumatic high vacuum butterfly valve is driven by compressed air. It changes the direction of the air path through the electromagnetic reversing valve, pushes the mechanical transmission of the piston rack and gear, drives the butterfly valve with the angular stroke output torque, and makes the opening and closing movement. So as to connect or cut off the air flow in the vacuum pipeline, it is a new type of pneumatic butterfly valve controlled by pneumatic actuator at present, which is divided into double acting and single acting (spring return) cylinders, with optional feedback signal device and electric valve positioner.
The applicable working medium is air and non corrosive gas.
