KF/ISO Flanged SS Million Cycle Gate Valves (Pneumatic)
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
