Aerospace Valves and Components

Oxygen/Nitrogen Filler Valves

The liquid oxygen and nitrogen filler valves are specifically designed to service liquid oxygen and nitrogen systems. These valves are for military aircraft and the large valve pictured weighs approximately 3 pounds. The valves automatically open and close when activated by the mating component.


High and Low Pressure Relief and Check Valves

Relief valves are designed for use on Air Force and Navy liquid oxygen converters and other cryogenic systems. Features include ANPT threaded inlet and outlet ports, internal filter and corrosion resistant steel. Valves are set at the factory in various operating pressure ranges from 80 to 430 psig. Check valves are designed to provide a positive directional flow for liquid oxygen or other gaseous systems operating in pressure ranges from 0 to 3000 psig.


Manual Globe Valves

All cryogenic systems need reliable service, build-up and venting globe valves. These globe valves are manufactured in various sizes from 1/4 inch up to 1 inch ANPT port sizes. Materials include a bronze body, stainless steel stems and Kel-F seats. Maximum operating pressure is 55 psig and capable of withstanding a hydrostatic pressure of 1 1/2 its operating pressure without leakage.
