●High temperature and high pressure resistance: Made of high-temperature alloys, heat-resistant steel and other materials, it can withstand high temperature and high pressure differences. The general temperature resistance range is from -60 ℃ to 538 ℃, and the pressure resistance level ranges from PN16 to PN420.
●Reliable sealing: The valve seat features a metal-seated design, ensuring excellent sealing performance under high temperatures and high pressures.
●Wear resistant and erosion resistant: The surfaces of key components such as valve cores and seats are hardened or made of wear-resistant materials, which can resist the erosion and wear of high-temperature and high-pressure fluids.
● Flexible operation: The valve stem transmission part adopts high-temperature resistant materials and self-lubricating structure, ensuring that the valve is easy to operate and flexible to open and close under high temperature and pressure.
●Fire and static electricity prevention: Some high-temperature and high-pressure ball valves have fire and static electricity prevention functions, which can prevent safety accidents caused by fire or static electricity.

The Concentric butterfly valve is an industrial valve used for the on-off and flow control of pipeline systems. It is widely applied in fields such as petroleum, chemical industry, metallurgy, and hydropower. Its core structural feature is that the axis of the valve stem, the center of the butterfly plate, and the center of the body are on the same axis, featuring simple manufacturing and balanced opening and closing torque. By selecting different materials for the valve plate, valve stem, and sealing seat, it can be adapted to various different working environments, such as desulfurization, vacuum, and seawater desalination systems.
The Side Entry Trunnion mounted ball valves are quarter-turn valves used to stop the flow of medium in pipelines. RAYS is the real API 6D valve manufacturer for the Trunnion mounted ball valve. These valves feature a round or spherical disk in the center that rotates to start or stop the flow. This disk is called a ball and it features a hollow center. Ball valves are extremely versatile and are commonly used in industrial applications where tight shut-off is required.
The dual plate check valve features two semicircular, spring-loaded valve discs mounted on a central vertical pivot. When the valve opens, the force of the fluid and the spring act at the center of the disc, causing it to open from the base first. This design minimizes wear on the seal during opening, enhancing its durability. As the flow decreases, the discs slowly move back towards the seat due to the spring's force, ensuring a gradual closure. During backflow, the increased force on the discs leads to a faster closure, effectively reducing the risk of water hammer and hydraulic shocks. The spring’s force closes the top end of the disc first, preventing damage at the disc's base and prolonging the seal's lifespan.
