Pneumatic 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 * Can withstand baking to 200° C (copper bonnet seal), 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 Pneumatic models also feature * Air to open, air to close operation; 60–80 psi air pressure opens the valves * 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.
