Cryogenic valves, except check valves are supplied with extended bonnet with a sufficient gas column length. Usually supplied by the user, to eliminate any chance of frosting of the packing area.
The cryogenic valves are installed on applications involving the production, transport and storage of liquefied gases such as oxygen, nitrogen, argon, natural gas, hydrogen or helium down to -254ºC.
The cryogenic valves are designed with compliance of ASME B16.34 and BS 6364. The cryogenic tests are performed in fully equipped in-house facilities, according to BS 6364.
