Conval offers standard Clampseal® Cryogenic Valves for high-pressure, low-temperature applications to -425F. This is below the temperature at which nitrogen liquifies, and the temperature used in many cryogenic processes in liquified natural gas (LNG), manufacturing, heat treating and vaporizing. Custom cryogenic valves, requiring special testing, are also available for even lower temperatures.
Clampseal Cryogenic Valves are available in 1/2“ through 4” sizes with socket weld, butt weld or special ends. Pressure ratings include ASME class through 2500#, ASME B31.3, ASME B16.34, and MSS SP-84. Standard materials include forged stainless steel, SA 182 and F316. Special pressure classes and materials are available. Features include metal-to-metal pressure seal bonnet; solid Stellite seating surfaces; single-piece gland; in-line servicing; and two-year warranty.
