900X emergency shut-off valve is a kind of valve used to allocate water supply direction in the water supply system in parallel with fire water and domestic water. When a fire breaks out, a large amount of water is urgently needed for fire fighting. The 900X emergency shut-off valve immediately cuts off domestic water to ensure sufficient fire fighting water. When the fire stop water pressure is reduced, the valve automatically opens, showing a normally open state, and the domestic water supply is restored. The valve makes the system need not set up a special fire separate water supply network, greatly saving the construction cost and water consumption. Valve control sensitivity is high, safe and reliable, easy debugging, long service life.
