This regulating valve adopts a pressure-balancing type valve core design, significantly reducing the operating torque. Combined with a high-precision guiding system, it achieves a regulation accuracy within 0.5%. The unique low-temperature compensation structure effectively counteracts the material shrinkage effect, ensuring stable performance across the entire temperature range. The valve internals are treated with a special surface treatment process, increasing the wear resistance by more than three times.

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.
Compared with other valve products, High Temperature and High Pressure Slab Gate Valve is characterized by high temperature and high pressure. Among them, grooved flange is designed as a unique self-tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The high-temperature and high-pressure gate valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the sealing surface of 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 structure adopts a short pattern, the valve gate is light in weight, and the pipe support frame can be saved. Diversified Drive Modes: Electric, gearbox, hydraulic and pneumaticcan be selected at will. High performance sealing combination packing: The combined packing sealing system isadopted to greatly improve its sealing performance.
