UHV gate valve

Series 10 all-stainless-steel UHV gate valves incorporate smooth, camless sealing to distribute pressure evenly around the plate for minimal closing shock and wear. Incorporating a vulcanized seal rather than an O-ring, the mechanism is bellows-sealed with no lubricants. Fully bakeable to 250?C open and 200?C closed, the valves can be equipped with manual or pneumatic actuators and can be mounted in any position. Available in sizes from 2.5 to 16 in. I.D., they are offered with CF, ISO, and ASA flanges; they exhibit a leak rate of <5 ? 10-10 mbar/ls and are rated for 50,000 cycles between maintenance.
