Electromagnetic Bellows Sealed SS Angle Valves (CF flanged)

Reliable, economical, general-purpose components for HV and UHV applications requiring cleanliness and corrosion resistance.

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

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

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.
