Description Pneumatic Angle Poppet Valves – HV, ISO-LF, Double Acting Isolation Poppet Valves are typically used as ‘shut-off’ devices and are installed in roughing and fore lines 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. Available in a wide range of sizes from ¾” to 2” orifice > 1 million cycles between service intervals Compact, low profile, small footprint design Spring returned to ‘closed’ during power / air failure High purity, dry valve system with a self-lubricating mechanism, significantly reduces particle generation. These valves are all double-acting.
