ISO 100 Bellows Sealed Angle Valve Pneumatic Actuation

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

• Standard spring-to-close operation; 60–80 psi air pressure opens the valves
• Require a solenoid (sold separately, see accessories)
