●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 -196 ℃ to 800 ℃, and the pressure resistance level ranges from PN10 to PN100, or even higher.
●Reliable sealing: The valve seat sealing surface adopts special materials and processing technology, such as metal hard seal or soft seal, to ensure good sealing performance under high temperature and high pressure.
●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.

An energy-saving control valve without external energy supply, used for non-corrosive liquids and gases with a temperature of ≤ 200℃ for differential pressure control devices. The valve opens or closes when the differential pressure increases.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
The Side Entry Cryogenic Trunnion Mounted Ball Valve fixed ball valve is a type of fixed ball valve that adopts an upper mounted structure. The ball is installed and disassembled through the upper part of the valve body, and can work stably under ultra-low temperature conditions. When closed, the valve stem drives the ball to rotate, making the hole on the ball perpendicular to the valve body channel, thereby cutting off the medium; When opened, the valve stem drives the ball to rotate 90 °, aligning the hole on the ball with the valve body channel, and the medium can pass through.
