Cryogenic valves are specially engineered and designed for piping systems used in the storage and transport of liquefied gasses such as LNG and liquid nitrogen and oxygen. Spire Industrial Equipments Co. Cryogenic valves faces the harsh conditions of services involving temperatures down to - 254o C. The main structural feature of these valves is an extended bonnet with an enclosed vapor chamber to isolate & eliminate any chance of frosting of packing. The presence of bleed hole in the Gate valves wedge helps equalize the body cavity pressure with the upstream pressure . Liquid nitrogen testing facilities go much further to assure proven performance in this most demanding application.
