Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes. Ultra-low temperature regulating valve:
● Adopting elongated valve cover to prevent cold conduction and freezing of packing, thereby eliminating the adverse impact of ultra-low temperature on the sealing performance of the stuffing box;
● Main components undergo hardening treatment, ultra-low temperature treatment, and ultra-precision processing to ensure precise regulation of flow and pressure.
● Passed strict ultra-low temperature deep cryogenic tests to guarantee stable operation under extreme conditions, ensuring safety and reliability.

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.
The Cryogenic Gate Valve is a type of equipment used for full opening and full closing operations. The opening and closing element of the low-temperature gate valve is a gate plate. The movement direction of the gate plate is perpendicular to the flow direction of the fluid. The gate valve can only be operated in full opening and full closing positions, and cannot be used for regulation or throttling. The gate plate has two sealing surfaces. The most commonly used type of gate valve has two sealing surfaces forming a wedge shape, and the wedge angle varies with the parameters.
The Insulation Jacket Ball Valve is specially designed for pipeline systems that require maintaining the temperature of the medium. It is made of high-quality stainless steel or carbon steel and combines with precise processing technology to ensure reliable sealing and smooth control under high-temperature and high-pressure conditions. The valve body adopts a jacketed insulation structure and can be filled with steam or heat transfer oil, effectively reducing heat loss. It is suitable for high-temperature fluid transportation systems in industries such as chemical, petroleum, heat supply, and pharmaceuticals. The structure is compact, the opening and closing is rapid, the sealing performance is excellent, and it is an ideal control valve for high-temperature fluid pipelines.
