Guq series pneumatic vacuum (pressure) ball valve is applicable to connect or cut off the medium flow in the pipeline in the vacuum system. The valve is powered by compressed air. By controlling the pneumatic components to change the direction of the air path, push the mechanical transmission of the piston rack and gear, and drive the ball valve to do the opening and closing movement with the angular stroke output torque. The valve is straight through type, sealed by spherical surface, so it can be used in vacuum state or low pressure state, and can be installed at any position. The air cylinder is divided into double acting and single acting (spring return). It can be equipped with feedback signal device and electric valve positioner.
Applicable working medium is acid and alkaline gas or liquid.
