GUD series pneumatic vacuum ball valve is applicable for the medium flow of connecting or cutting off the pipelines in the vacuum system.

This valve uses compressed air as the dynamics. It changes the gas circuit direction through the control of pneumatic components. It pushes forward the air cylinder to make the ball valve have start-stop motions. The straightway valve relies on spherical sealing. Therefore it can be used in both the vacuum and low pressure conditions. It can also be installed in random position. It has Double-acting and Single -acting(Spring return) air cylinder with optional Singal feedback device and electric valves servo.

The applicable active medium of this valve are acid, alkali gas or liquid.
