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.
