It is mainly used for storage and transportation of oil and gas in the chemical industry, metallurgy, paper making, food processing, shipbuilding and other industries, used to open or close, and with pneumatic and electrical devices can also achieve the long-distance operation, to ensure personal safety.
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.
The upper mounted ultra-low temperature floating ball valve is a valve suitable for ultra-low temperature environments, mainly used to connect or cut off low-temperature media.
