RAYS cryogenic ball valve with extended bonnet ball valve will bring you a huge gain in the field of cryogenic LNG service. Service temperature from -51° to -196°C (-59,8° to -320,8°F) with extended bonnet design.
The Comodity Cast Steel Gate Valve is mainly composed of valve body, valve cover, valve wedge, valve seat and valve stem. The two sealing surfaces are wedge-shaped gate valves. The purpose of the wedge is to improve the auxiliary seal load, to achieve both high medium pressure sealing and low medium pressure sealing. The valve body of the wedge valve is provided with a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
Designed specifically for deep cold medium working conditions such as LNG, liquid nitrogen, and liquid oxygen, it adopts special stainless steel or low-temperature alloy valve bodies. Through deep cold treatment, it ensures reliable sealing even in an extreme environment of -196℃. The innovative lateral maintenance port structure allows for quick replacement of the sealing components without disassembling the valve, significantly improving maintenance efficiency. The optimized double eccentric butterfly plate, combined with multi-level metal hard seals, achieves zero leakage and long service life under ultra-low temperature conditions. At the same time, it is equipped with a longened valve stem heat insulation structure, effectively blocking the conduction of cold energy.
