Manual Bellows Sealed SS Angle Valves (ISO 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

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

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