11000 Series Stainless Steel Gate Valves
The KF, ISO-F, ISO-K, ASA and JIS flanged 11000 Series Standard Cycle 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. These valves can also be configured for higher temperatures.
