Electromagnetic 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

  • Helium leak tested before shipment using a helium mass spectrometer with a sensitivity of 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

Electromagnetical models also feature

  • Small valves operate on 24 VDC
  • Designed for a variety of high vacuum processes requiring a simple, compact, high conductance electric valve to 10-9 torr
  • Ideal for pump systems, portable vacuum stands and benchtop analytical systems
  • Easy installation—no pneumatic connections, gas bottles, or house air supply lines required
  • Unique coil saver design minimizes the heat traditionally associated with conventional electric valves
  • An option for applications where temperature sensitive gauge isolation is critical

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.
