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)
