The swing-type valve disc design is combined with a low-inertia structure to ensure rapid closure and reduce water hammer effects, thereby enhancing system safety. The sealing surfaces of the valve seat and valve disc are treated with hardening or PTFE composite materials, which adapt to the ultra-low temperature contraction characteristics and maintain long-term sealing performance. The optimized flow path design reduces pressure loss, improves the efficiency of medium flow, and simultaneously reduces the risk of icing. The overall structure is compact, supporting horizontal or vertical installation, meeting the requirements of different pipeline configurations, and suitable for high-demand applications of one-way cutoff for deep-cold media.

The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
The Silenct Check Valve is a valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent the backflow of the medium. Belonging to an automatic valve, its main function is to prevent medium backflow, prevent pump and drive motor from reversing, and prevent the release of container medium. Check valves can also be used on pipelines to supply auxiliary systems where the pressure may rise above the system pressure.
RAYS Top Entry Cryogenic Trunnion Mounted Ball Valve is a type of valve widely used in cryogenic piping systems, especially suitable for the on/off control of cryogenic liquid or gas media such as liquefied natural gas (LNG), liquefied petroleum gas (LPG), liquid hydrogen, and liquid oxygen. Its design features include a top-entry valve body structure for easy online maintenance, an extended bonnet design to prevent condensed water from flowing into the insulation layer, a live-loaded sealing structure design for the valve stem, and a special design of the valve seat assembly.
