●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 Non-Rising Stem Gate Valve is also called the rotating stem gate valve. Stem and nut are arranged on the gate plate, handwheel rotation drive valve stem rotate to lift the gate, usually there is a trapezoidal thread at the bottom of the valve stem and the rotation movement is turned into a linear motion through the limit slot between the valve stem and the gate body and the gate body and the gate, that is, the operation torque is turned into operation thrust. When the valve is turned on, when the height of the gate is equal to the diameter of the valve 1: 1: 1, the channel of the fluid is completely unblocked, but at the run, this position cannot be monitored. In actual use, the vertex of the valve stem is used as a sign, that is, the position that is unmoved as its full opening position. The non-rising stem gate valve has the design characteristics of the ordinary wedge-type gate valve. The valve body has a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
The valve disc of the Cryogenic Swing Check Valve adopts a cantilevered swing structure, combined with precisely machined valve seat sealing surfaces, to achieve rapid response and reliable sealing, effectively preventing the reverse flow of the medium. The overall design of the valve complies with international standards such as BS 6364 and ISO 28921, and is suitable for low-temperature conditions in air separation plants, liquefied natural gas storage and transportation, and the chemical industry.
Self-Operated Micro-Pressure Regulator does not require additional driving energy and is a kind of energy-saving control device; it is a specialized product for current most popular nitrogen sealing system of storage tanks.
