China Vacuum Gate Valves,KF Vacuum Valves,ISO Vacuum Valves Factory

China Vacuum Gate Valves Suppliers

The KF, ISO-F, ISO-K, ASA and JIS flanged Series Gate Valves are designed for high vacuum applications. These valves provide valving for cryopumps, turbo pumps, ion pumps and other applications requiring clean, low outgassing valves. Metal-sealed CF Flanges provide compatibility with UHV systems when pressure ranges approximate 1 x 10-10 mbar and higher bakeout temperatures of 200°C are needed. Vacuum Gate Valves including Vacuum Gate Valves, KF Vacuum Valves, ISO Vacuum Valves which are the best choice for isolating gauges, foreline traps, petrochemical, abatement scrubbers, vacuum coating roughing lines, food processing lines and many more industrial applications.
