Ductile Iron Diaphragm Type Adjustable Pressure Reducing And Stabilizing Valve
Product introduction:
Fire fighting valve products are control accessories on industrial and building pipelines. Fire fighting valve is the most important controlled accessory on industrial and building pipelines, normally consisting of valve body, opening and closing mechanism, and valve cover. Simple structure and reliable sealing.
Most fire valves are connected with clamps, making the complex valve installation and pipeline connection process simple, fast, and convenient. Taking pipeline connection technology a big step forward.
The F8745X series multifunctional water pump control valve is installed at the outlet end of the water pump, sequentially achieving functions such as slow opening, full opening, quick closing, and slow closing. It is mainly used on the outlet pipeline of water pumps in high-rise building water supply systems and other water supply systems to prevent and reduce water hammer in the pipeline during water pump opening and closing, prevent water backflow, protect the water pump, and maintain pipeline safety.
The F8745X series multifunctional water pump control valve consists of a main valve, a regulating valve, and a connecting system. The valve body adopts a DC type valve body, and the main valve control room is a diaphragm or piston type dual control room structure. The control room is added to the general hydraulic control valve, which increases the control function of the main valve and realizes multi-functional control of the water pump outlet, such as slow opening, full opening, slow closing, and cut-off. It realizes multi-functional control of the water pump outlet with one valve and one adjustment.

Product features:
1. The prevention of water hammer is effective by integrating technologies such as slow opening, check and quick closing, and slow closing to eliminate water hammer. This prevents damage to the water supply pipeline and pump caused by pump failure and backflow during pump shutdown, as well as water hammer.
2. Easy to operate, there is no need to equip the valve with an additional electrical control system. The valve automatically and sequentially completes control functions with the opening and stopping of the water pump. By setting the opening of the regulating valve, appropriate control parameters can be obtained.
3. The valve body adopts a full channel, direct current, and streamlined design. Low hydraulic loss and good energy-saving effect.
