The Fill, Buildup and Vent Valve is an automatic-acting type valve that provides a safe, rapid method to control liquid and gaseous oxygen flow during the fill-up and operation of cryogenic converters.

Features

• Meets and/or exceeds functional and environmental requirements of MIL-PRF-25961• Designed to mate with the standard liquid oxygen ground handling device per MIL-PRF-38201• Check valve in the fill port preventing reverse flow of liquid gases• Constructed of aluminum with stainless steel poppets and Teflon seals• Functions satisfactorily without leakage after 880 mating cycles with filler valve conforming to MIL-PRF-38201
