The power station swing check valve has a small fluid resistance, and the internal medium channel of the valve body is directly connected. The
medium does not change its flow direction when it flows through the stop valve. The pressure is self-tightly sealed, and both ends of the valve are
welded connections. The valve petals are closed quickly, the water hammers are low pressure, the body structure is simple, the production is better, the sealing performance is good, and the dense cover is less erosion. The scope of applications is wide.
Application Scenarios: The power station swing check valve is generally used in places with harsh service conditions, such as high temperature and high pressure thermal power plants, power industry, petroleum refining and other fields.

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.
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.
