GUQ series pneumatic vacuum ball valve is applicable for the medium flow of connecting or cutting off the pipelines in the vacuum system.
This valve takes the compressed air as the motive power. It changes the gas circuit direction through the control of pneumatic components. It pushes forward the executive gas 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 any wanton position.

The applicable operating media are acid, alkali gas or liquid. Applicable media temperature: -25℃～+230℃ Please refer to the below table for the main technical performance & parameters of GUQ series pneumatic vacuum ball valves.
