Product introduction
900X emergency shut-off valve is a valve used to allocate the water supply direction in the parallel water supply system of fire water and domestic water. In case of fire, the fire is in urgent need of a large amount of water, and the 900X emergency shut-off valve immediately cuts off the domestic water to ensure sufficient fire water; When the pressure of fire water is reduced, the valve will automatically open and be normally open to restore domestic water supply. The valve makes it unnecessary for the system to set up a separate fire water supply network, which greatly saves the construction cost and water consumption. The valve has the advantages of high control sensitivity, safety and reliability, simple commissioning and long service life.
