    LNG & Cryogenic

    LNG & Cryogenic

    LNG & Cryogenic

    LNG and cryogenic systems operate at extremely low temperatures down to -196°C, where material brittleness, thermal contraction, and sealing reliability become critical. Valve failure in cryogenic service poses serious safety risks.

    Our cryogenic ball valves are applied in LNG storage tank loading/unloading lines, cryogenic process pipelines, liquefaction and regasification units, and transfer and distribution manifolds.

    Why Choose SLVCN Valves?

    Cryogenic-tested ball valves qualified down to -196°C
    Extended stem and low-temperature sealing design for safe operation
    Metal-seated DBB valves for zero leakage under cryogenic conditions
    Pressure-relief chambers and multiple cryogenic treatments on pressure parts
    Proven experience supplying valves for LNG terminals and cryogenic facilities, supported by in-house cryogenic testing workshops
