Pneumatic Bellows Sealed SS Angle Valves (Tube Ends)

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

  • Leak Rate: 2 x 10-10 std. cc/sec.
  • Poppet seals are fluorocarbon o-rings
  • Bonnet seals can be fluorocarbon or copper gaskets (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)

NOTE: We list a wide variety of standard tube sizes from 3/8" to 4". Other sizes and valves with mixed flanges are available on request.
