Product Listing

HV Series

MDC Europe Products is proud to introduce our new 100K Cycle Stainless Steel Circular Gate Valve product line. MDC’s 100K Cycle Gate Valves are a cost-effective alternative to our Million Cycle Gate Valve product line, offering the same reliability and quality you have come to depend on. Every valve is made in the USA to MDC’s rigorous quality standards. 100K Cycle Gate Valves have been designed for use in high and ultra-high vacuum applications with low cycle requirements (< 100,000 cycles until service). These valves are ideal for isolation of cryopumps, turbo pumps, ion pumps, and other applications requiring clean, low outgassing valves. Metal-sealed Del-Seal™ CF flanges provide compatibility with UHV systems when pressure ranges approximate 1 x 10-10 Torr (mbar) and higher bakeout temperatures of 200°C are needed. 100K Cycle Gate Valves can be configured for higher temperatures, come in a range of sizes from 5/8” (DN16) To 20” (DN500), and are available in manual or pneumatic actuator configurations. Valve flange options include standard KF, ISO, Del-Seal™ CF or custom.
