This high pressure charging valve is robust and corrosion resistant, and is constructed from a combination of 15-5 PH and 300 series stainless steel components with nitrile rubber o-rings with Teflon back-up rings for sealing and support. Actuation of the valve is achieved by turning a nut which jacks the valve stem open, or closed, against a metal-to-metal, bubble-tight seat. Charging is done by simply removing thestem cap and connecting a gas source to the stem end. The design also incorporates an audible safety feature that warns the user of unreleased air pressure when the valve is being removed from its installation boss. Designed for 345 bar pressure vessels, the valve weighs 34.5g. The valve is supplied with mounting threads for use with AS5202-05 standard ports and has pressure ratings of 345 bar (operating), 690bar (proof) and 862 (burst).
