Cryogenic Ball Valve

Cryogenic Ball Valve

Cryogenic Ball Valves are engineered specifically for extremely low-temperature applications, including LNG and cryogenic gas processing systems. Designed with an integral bonnet extension, these valves prevent cryogenic liquids from reaching the stem packing, allowing the liquid to vaporize safely before it can affect the valve’s moving parts. This feature minimizes energy loss and protects the valve from malfunction due to thermal stress.

Built to meet BS 6364, MESC 77/200, ISO 28921-1, and customer-specific requirements, these valves maintain tight shut-off performance and structural integrity under the severe thermal fluctuations typical in cryogenic service. The robust design also ensures minimal thermal deformation of internal components, making them ideal for critical LNG field operations.
