Valves
Forged Cryogenic Gate Valve
Features
Remy's forged cryogenic gate, globe valves are specially designed to handle the technical problems that arise in the production, transport and storage of liquefying gases such as Oxygen, Nitrogen, Argon, Natural Gas,. All basic design features of ENE forged cryogenic gate, globe valves outlined in this catalog are adapted to special service conditions at cryogenic temperatures. Body and bonnet: stainless steel (A182 F316L) forgings used for bodies and bonnets offer excellent impact strength, minimal heat loss and protection against corrosion.
