Pneumatic Bellows Sealed SS Angle Valves (KF flanged)
Reliable, economical, general-purpose components for HV and UHV applications requiring cleanliness and corrosion resistance.
In the open position
- Edge-welded bellows and valve seat move out of the gas path thereby achieving high conductance
Features
- Feature fluorocarbon o-ring seat seals, bellows-sealed shafts, and bonnet seals (select copper for higher temperature bakeout and better ultimate vacuum)
- Normal repairs can be made without removing the valve body from the system
Pneumatic models also feature
- Spring-to-close operation on valves ≤ 2", 2-1/2" and larger are air-to-open air-to-close
- Require a solenoid (sold separately, see accessories)
