Manual Angle UHV CF Poppet Valves

Description Manual Angle UHV CF Poppet Valves Isolation Poppet Valves are typically used as ‘shut-off’ devices and are installed in roughing and forelines where most applications connect to an exhaust system and there is a potential risk of contamination. In addition, special design ‘dry valves’ offer the necessary protection for vacuum systems when back streaming occurs. The Poppet Valves use edge welded bellows as standard and provide optimum conductance with a small footprint design. UHV version utilizes an oxygen-free high conductivity copper gasket for the bonnet seal. > 1 million cycles between service intervals. – Compact, low profile, small footprint design. – High purity, dry valve system with a self-lubricating mechanism, significantly reduces particle generation. Offered with CF flanges. Note, the “CL” distance is the centerline to centerline distance of the ports in millimeters (mm).
