Description Pneumatic Angle Poppet Valves – CF 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. Choose between the HV or UHV version. The UHV version features an OFHC bonnet seal. Note in the Technical Specs tab whether valve is single or double acting.
