The high vacuum flapper valve is used to switch the vacuum line on and off. The principle of operation is to close and open the valve stem by moving it up and down. High vacuum flapper valves are mainly pneumatic, electric, manual, and other drive methods, the structure is mainly right-angle, straight-through, oblique angle. Such valves have the advantages of simple structure, reliable sealing and convenient disassembly and assembly.

Anti-protruding seal structure design can prevent the seal ring from falling off; Compression seal groove structure, introduce the processing and installation process; Special bellows seal, reliable sealing, cost control; Integrated cylinder structure, reduce cost and weight; Special electromagnetic Valve installation, beautiful and economical; micro-switch sensing, PLC control; overall aluminum material, reduce weight, control costs; no welding structure, reduce leakage, improve vacuum
