Conval, a global leader in high-performance valves for the world's most demanding applications, offers Clampseal® Cryogenic Valves for high-pressure, low-temperature applications to -320F. This is the temperature at which nitrogen liquifies, and the temperature used in many cryogenic processes in liquified natural gas (LNG), manufacturing, heat treating and vaporizing.
Clampseal Cryogenic Valves are available in 1/2" through 4" sizes with socket weld, butt weld or special ends. Pressure ratings include ASME 1500 and 2500, ANSI B31.3, ANSI B16.34, and MSS SP-84. Standard materials include forged stainless steel, SA 182 and F316. Special pressure classes and materials are available.
