Pneumatic Million Cycle SS Gate Valves (CF flanged)

Used with cryopumps, turbomolecular pumps, and ion pumps; ideal for applications requiring clean, high-vacuum, low-maintenance valves.

  • Rugged valves share the design features of the standard valves
  • Enhanced to withstand 1 million+ cycles before requiring service
  • Bellows reinforced for longer operating life
  • All moving joints are made of 304 stainless steel, hardened to increase durability, reduce particulate generation, and provide smoother actuation
  • Maintain closed status in the event of a power failure
  • Feature fluorocarbon seals (bakeable to 150° C) and electropneumatic operators
  • Body-mounted solenoid with manual override provides easy control
  • 120 VAC Solenoid incorporates speed controls for smoother actuation
  • 1.5" to 12.0" models are equipped with magnetic reed switches for position indicator

NOTE: Available options include larger sizes, microswitches, custom flanges, and latching-type solenoids. Please call if ordering options.
