Vacuum Baffle Valve
The high vacuum baffle valve is used to connect or cut off the vacuum pipeline. Its working principle is to close and open the valve by the up and down movement of the valve stem. High vacuum baffle valves are mainly driven by pneumatic, electric, manual, etc. The structures are mainly right-angle, straight-through, and oblique. This kind of valve has the advantages of simple structure, reliable seal, convenient disassembly and so on.
Anti-stripping seal structure design can prevent the sealing ring from falling off; compact seal groove structure, introduces the processing and installation procedures; special bellows seal, reliable sealing, cost controllable; integral cylinder structure, reducing cost and weight; Valve installation, beautiful and economical; micro switch induction, PLC control; overall aluminum material, reduce weight, control cost; non-welded structure, reduce leakage points, improve vacuum
