Vacuum valve working principle:
The United States of America Ou vacuum valve is suitable for the vacuum system to connect or cut off the pipeline medium flow. The valve is a straight through type manual ball valve, by a spherical sealing, which can not only be used in vacuum condition, can also be used in a low pressure state, and can be installed at any position. Applicable medium with acid, alkaline gas or liquid.
The main advantages of imported vacuum valve:
Standardized, modular design, easy to replace and repair;
Easy to clean design;
Manual ultra-high vacuum valve adopts the energy-saving design, small volume.
Vacuum valve performance:
