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
