Air charging valve suits high-pressure applications
Lee Products is launching a high-pressure air charging valve that provides the capability for a reliable manually-operated valve that facilitates the charging or bleeding of a high-pressure gas system. The valve's easy-to-use function and leak-proof characteristics make it a good choice for charging or discharging pressure vessels in aerospace, oil tools and Formula One racing applications.
Robust and corrosion resistant, the valve is constructed from a combination of 15-5 PH and 300 series stainless steel components with nitrile rubber O-rings and Teflon back-up rings for sealing and support.
Actuation of the valve is achieved by turning a nut that jacks the valve stem open, or closed, against a metal-to-metal, bubble-tight seat. Charging is performed by simply removing the stem cap and connecting a gas source to the stem end. The design also incorporates an audible safety feature that warns users of unreleased air pressure when the valve is being removed from its installation boss.
Designed for 5000psi pressure vessels, the Lee Air Charging Valve is a lightweight device weighing just 34.5g compared with 47.6g for other types of design. It therefore provides the same functions in a significantly smaller overall package. The valve is supplied with mounting threads for use with AS5202-05 standard ports and has pressure ratings of 5000psig (operating), 10,000psig (proof) and 12,500 (burst).
Special custom designs are also available on request.
