Product IntroductionThis product is designed and manufactured by our professional technicians with reference to advanced counterparts from the US, France and domestic markets. It is suitable for industrial and mining enterprises, high-rise buildings, domestic water supply and fire protection systems. In scenarios requiring static and dynamic pressure reduction, it can replace intermediate water tanks, saving construction costs and expanding usable building space.The valve body features a full-channel streamlined design, ensuring low fluid resistance and large flow. It adopts hydraulic operation: water pressure in the pipeline automatically drives the main valve disc to move up and down, controlling the valve port opening and regulating downstream pressure to maintain it at the value set by the pilot valve spring. When downstream pressure exceeds the set value, the pressure reducing valve shuts off automatically. It delivers stable outlet pressure (P2) regardless of fluctuations in inlet pressure (P1) or changes in downstream flow. Additionally, the pilot valve allows a wide outlet pressure adjustment range (10-80% of the inlet pressure), with stable operation and no water hammer.Product diagram of 200X piston pressure reducing valve

Product IntroductionThis product, developed by our engineering and technical personnel through the introduction of new technologies as well as improvements in manufacturing processes and structures, has reached the advanced level of international similar products. The valve body adopts a full-channel streamlined design, featuring low fluid resistance and large flow rate. It uses hydraulic operation in terms of transmission mode, that is, the water pressure in the pipeline is utilized to automatically control the vertical movement of the main valve disc and adjust the opening of the main valve port. The main valve is installed in the pipeline for controlling flow in water supply and distribution pipelines. By presetting and adjusting the pilot regulating valve and a fixed flow rate of the pilot valve on the upper part of the valve, the flow rate through the main valve can be kept constant without being affected even if the pressure upstream of the main valve changes. In a word, this product is an ideal choice for domestic water supply, fire protection systems and industrial water supply systems.Product diagram of 400X piston flow control valve

Product IntroductionThis valve is a new-type product developed by our engineering technicians with reference to advanced counterparts from the US, France and domestic markets. It adopts hydraulic operation and automatic control via pressure difference in the control pipeline to automatically open/close and shut off the main valve, ensuring upstream pressure does not exceed a set value.The valve body features a full-channel streamlined design, offering low fluid resistance, excellent sealing performance and sensitive automatic opening/closing response. Its key advantage is dual functionality as both a pressure relief valve and a pressure sustaining valve:As a pressure relief valve, it releases pressure in water supply pipelines exceeding the pilot valve’s safe set value, maintaining pressure below the safe threshold to prevent pipeline/equipment damage from overpressure or sudden pressure surges. It is applicable to fire test circulation systems in high-rises and other water supply systems to avoid system risks from excessive water pressure.As a pressure sustaining valve, it maintains upstream water supply pressure above a set value to ensure stable pressure in upstream supply areas, mainly for urban low-pressure water supply zones.In summary, it is an ideal product for water supply systems.

Product IntroductionThis product is designed and manufactured by our factory's engineering and technical personnel with reference to advanced products of the same type from the United States, France and other countries. It is suitable for parallel water supply systems in industrial enterprises, domestic water supply and fire water supply. During fire water supply, the valve automatically closes urgently to cut off domestic water supply and ensure fire water demand. After the fire is extinguished, the valve automatically opens to resume domestic water supply. It can replace the intermediate water tank in occasions requiring static pressure and dynamic pressure reduction, saving the cost of building intermediate water tanks and expanding the usable space of buildings. The valve body adopts a full-channel streamlined design, featuring low fluid resistance and large flow rate. Hydraulic operation is adopted for the transmission method—utilizing the water pressure in the pipeline to automatically drive the main valve disc up and down, control the valve port opening, adjust the downstream pressure, and maintain the downstream pressure at the set value of the pilot valve spring. When the downstream pressure exceeds the set value, the pressure reducing valve will automatically close. Regardless of fluctuations in the inlet pressure P1, a stable outlet pressure P2 can be output. It can adapt to downstream flow changes ranging from 10% to 80% of the inlet pressure, operating stably without water hammer impact.900X Piston-Type Emergency Shutoff Pressure Reducing Valve Product Drawing
