Function: This valve is a pilot-operated regulator that reduces and stabilizes a higher inlet pressure to a lower downstream pressure, regardless of flow rate or inlet pressure variations. When downstream pressure exceeds the control pilot's set limit, both the main and pilot valves close tightly, ensuring precise regulation.

The Diaphragm Water Pump Control Valve is an intelligent valve designed for installation at the outlet of water pumps in high-rise building water supply systems and other water supply applications. It prevents medium backflow, water hammer, and related phenomena. This multifunctional valve integrates the functions of an electric valve, check valve, and water hammer eliminator, significantly enhancing the safety and reliability of the water supply system. The valve incorporates the principles of slow opening, fast closing, and slow closing, effectively eliminating water hammer during pump startup and shutdown. By simply operating the water pump motor's start and stop buttons, the valve automatically adjusts to the pump's operating procedures, offering high flow rates and low pressure loss. The diaphragm design is suitable for valves with diameters up to DN600.
