Pneumatic Bellows Sealed SS Angle Valves (CF 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
  • Can withstand intermittent baking to 200° C (150° C Continuous), improving ultimate vacuum

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)
