Product Details

The Cryogenic Top Entry Floating Ball Valve is engineered for LNG, LPG, hydrogen, oxygen, and industrial gas applications operating at temperatures as low as -196°C. The extended stem design isolates the packing area from cryogenic exposure, ensuring long-term sealing integrity and operational safety in extreme low-temperature environments.

Its top entry construction enables in-line maintenance without removing the valve from the pipeline, reducing downtime in critical energy systems. The precision floating ball mechanism provides smooth torque performance and reliable bubble-tight shut-off.

Manufactured from high-grade stainless steel materials such as 316L and 304L, the valve is suitable for LNG terminals, air separation units (ASU), liquid nitrogen systems, and industrial gas pipelines. An advanced sealing packing system helps minimize fugitive emissions, while anti-static device, anti-blowout stem, and fire-safe design enhance overall safety performance.

Body, ball, seat, and stem materials can be customized according to specific cryogenic media and project requirements. All cryogenic valves undergo in-house low-temperature performance testing to verify sealing integrity and operational stability before delivery. This valve delivers a safe, durable, and maintenance-efficient solution for demanding cryogenic service worldwide.
