(Summary description)Safety and reliability are paramount in the design of LNG cryogenic valves, which are used in some of the most challenging environments. These valves are built to withstand extreme temperatures, ranging from -196°C to +85°C, and are constructed from high-quality materials such as CF3M, CF3, CF8M, and CF8 (equivalent to F316L, F304L, F316, and F304). These materials provide excellent corrosion resistance and durability, ensuring long-term performance in LNG, O2, N2, and Ar applications.

One of the critical safety features of LNG cryogenic valves is the pressure relief mechanism. Holes are punched at the upstream end of the sphere to ensure pressure relief in the middle cavity, preventing over-pressurization and potential valve failure. Additionally, holes on the bracket ensure a secure connection between the extended section and the middle cavity, eliminating hidden risks and enhancing overall safety.
The valve stem seal is designed with low-leakage packing, which is essential for maintaining the integrity of cryogenic systems. The disc spring pre-tightening structure ensures consistent sealing force, reducing the risk of leaks and enhancing the valve's reliability. Furthermore, the use of high-strength grade 2 studs for the middle cavity pressure fastener allows for precise control of the gasket's pre-tightening force, ensuring a secure and leak-free connection.
To guarantee the highest level of quality and safety, all pressure-bearing welds in LNG cryogenic valves undergo 100% radiographic inspection. This rigorous testing ensures that the valves meet the most stringent industry standards, providing users with confidence in their performance and reliability in critical cryogenic applications.
