400XA Model

Application: The main valve is installed in distribution pipelines where flow and pressure control are required, ensuring that the preset flow rate remains constant. It limits excessive flow to a predetermined value and reduces upstream high pressure to downstream low pressure. Importantly, fluctuations in pressure upstream of the main valve do not affect the flow rate downstream.

500X Model

用途: When the pressure in the water supply line exceeds the set pressure of the relief valve, the valve automatically opens to prevent damage to pipes and equipment caused by overpressure. It can be used as a relief valve in the fire-testing circulation system of high-rise buildings, helping to safeguard the system from potential hazards due to excessively high water pressure.

600X Model

Application: This valve is designed to be installed in pipelines, enabling remote-controlled opening and closing. It can replace bulky electric actuators traditionally used for operating gate valves or butterfly valves—offering a compact design, lightweight construction, simple maintenance, convenient operation, and reliable safety.

700X Model

Usage: Installed at the outlet of the water pump, this device first closes the main valve to 90% before the pump stops operating. Once the pump halts, the remaining 10% is closed again. This method effectively protects the pump by preventing water hammer, minimizing water-hammer noise, and avoiding pump reversal.

800X Model

Application: Used between the supply and return lines of air conditioning systems to maintain a consistent differential pressure, enhance system efficiency, and ensure the pressure difference remains precisely stable. This helps reduce system noise and prevents potential damage to equipment caused by excessive pressure differences.

900X Model

Application: This valve is designed for use in residential complexes with a water supply system that simultaneously provides both fire-fighting and domestic water. When fire-fighting water is needed, the valve automatically shuts down urgently, cutting off the domestic water supply to ensure uninterrupted fire protection. Once firefighting is complete, the valve reopens automatically, restoring normal domestic water flow. This system is more cost-effective than traditional separate fire-fighting water systems.

JD745X Model

Application: Used at the pump discharge lines in industrial, mining, enterprise, and high-rise building water supply systems—as well as other water distribution systems—to prevent media backflow and mitigate water hammer and water surge phenomena. It combines the functions of a shut-off valve, check valve, electric valve, and water hammer eliminator into one compact device. This product is especially suited for integration with automated pumping control systems, requiring no electrical controllers or external power sources—its operation remains fully automatic and follows standard procedures for opening and closing. Featuring three key mechanisms—quick-close, slow-close, and energy-absorbing chamber—it effectively reduces and eliminates water hammer effects, significantly enhancing system safety and reliability. This makes it an ideal solution for meeting the automation control requirements of modern system engineering equipment.

Model JH745X

Application: Used at the pump discharge lines in industrial, mining, enterprise, and high-rise building water supply systems—as well as other water distribution systems—to prevent media backflow and mitigate water hammer and hydraulic shock. It combines the functions of a shut-off valve, check valve, electric valve, and water hammer eliminator into one compact device. This product is especially ideal for integration with automated pumping control systems, requiring no electrical controllers or external power sources—instead, it operates fully automatically according to standard procedures. Featuring three key mechanisms—quick-close, slow-close, and energy-absorbing chamber—the device effectively prevents and eliminates water hammer, significantly enhancing system safety and reliability. It seamlessly meets the demands of advanced automation and control requirements in modern system engineering applications. Pressure ratings: PN 10, PN 16, PN 25

F745X-10/16

Application: This valve is designed for use in industrial, mining, enterprise, and high-rise building applications—specifically in automatic water supply systems for water tanks, reservoirs, and water towers. It can also serve as a circulation control valve for atmospheric-pressure boilers, precisely regulating the liquid level in water towers or reservoirs. When the water level reaches the preset threshold, the valve automatically shuts off; conversely, when the water level drops, the valve opens to refill, ensuring continuous and efficient water supply. The valve is easy to maintain, highly reliable, durable, and offers accurate liquid-level control. Its operation remains unaffected by water pressure fluctuations, while providing a tight seal that prevents leaks. Additionally, the float mechanism can be installed separately from the main valve for added flexibility.
