◎Excellent sealing performance, using metal bellows as the key sealing component, with its lower end welded to the valve stem assembly and its upper end connected to the
Plate welding forms a metal barrier to prevent fluid medium leakage and achieve zero
leakage of the valve stem
◎The main components such as the valve body are made of forged steel with high structural strength, resulting in a more uniform structure, better density and strength integrity, and dimensional errors small, with better performance compared to castings, able to withstand higher pressure and temperature
◎ Easy and reliable operation
The dual guarantee of long service life with corrugated pipe sealing and packing sealing
reduces the risk of leakage and lowers the frequency of maintenance; Valve body and
◎The minimum wall thickness design of the valve cover meets the requirements of relevant standards, ensuring the strength and rigidity of the valve under harsh working conditions such as high temperature and high pressur

The Cryogenic Single-seat Control Valve is specially designed for low-temperature working conditions ranging from -196℃ to +80℃. It features an integral forged valve body structure and is equipped with a bellows seal assembly to ensure reliable sealing under extreme temperature conditions. The valve core is designed with a parabolic or equal percentage flow characteristic, forming a precise fit with the hardened alloy valve seat to achieve precise control of the medium flow. The product complies with IEC 60534-4 and GB/T 4213 standards, and is suitable for precise regulation of low-temperature media such as LNG, liquid oxygen, and liquid nitrogen. The pressure rating covers ANSI Class 150 to 900, and is widely used in key areas such as air separation equipment and low-temperature storage and transportation systems.
Forged steel globe valve is a high-performance fluid control equipment, manufactured with high-quality forged steel materials and precision, integrating throttling and shut-off functions. Specially designed for high-pressure and high-temperature working conditions, it has the characteristics of compact structure, reliable sealing, and long service life, and is widely used in harsh working conditions in industries such as petroleum, chemical, and power.
The valve body is made of high-strength alloy steel or stainless steel, and is equipped with a precisely processed swing-type valve disc structure, enabling automatic control of the unidirectional flow of the medium. The optimized fluid dynamics design effectively reduces water hammer impact. The surface of the valve disc is clad with hard alloy to ensure reliable sealing under high-pressure and high-speed conditions. It is suitable for pipeline systems in industries such as petroleum, chemical engineering, and power.
