●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.

RAYS' rising stem ball valve is designed to operate without friction between the ball and the seat during opening and to achieve zero leakage when closed. This makes it well-suited for demanding conditions. The valve is made entirely of metal and is fire-resistant, capable of functioning in extreme temperatures ranging from -196°C (320.8°F) to 538°C (1000.4°F). It can handle media with particulates like sand and short fibers, and meets NACE standards for corrosion resistance, ensuring it can resist sulfide stress cracking in harsh environments. The valve also features a self-cleaning mechanism. When the ball is tilted away from the seat, the fluid flows 360° around the ball's sealing surface, effectively removing any debris. This prevents damage from high-speed fluid flows and keeps the sealing area clean. The rising stem ball valve is ideal for various applications including exhaust, fluid transfer, pipeline isolation, bypass, product segmentation, and emergency shutdowns, particularly where high switching frequencies and zero leakage in high temperatures are required.
The Cryogenic High-Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
The self-regulating control valve is an energy-saving control device that does not require external driving energy. It relies on the pressure or temperature of the medium being regulated as its power source, automatically adjusting according to set values based on changes in the medium. This valve integrates multiple functions of detection and control into one unit, forming an independent instrument control system. The self-operated control valve adopts a standard modular design. Our products are characterized by: standardization, serialization, and generalization. This achieves a high level of these three aspects. The components of the self-operated pressure regulator and differential pressure regulator are interchangeable. If the control conditions change, the spring & diaphragm components can be easily replaced. The accuracy of the self-operated control valve surpasses that of similar products, and it also offers high stability. Diversified product series: self-operated pressure regulator, self-operated micro-pressure regulator, self-operated temperature regulator, self-operated flow regulator, self-operated nitrogen-sealing valve, and self-operated (combined) regulator...
