Brief introduction of 900X emergency shut off valve: 900X emergency shut-off valve is a kind of valve which is used in the water supply system of fire fighting water and domestic water in parallel, and is used in the direction of water supply by users. In case of fire, a large amount of water is urgently needed for fire fighting. Domestic water should be cut off immediately to ensure sufficient water for fire fighting; When the fire stop water pressure decreases, the valve will automatically open, in a normally open state, to restore domestic water supply. The system does not need to set up a separate fire water supply network, which greatly saves the construction cost and water consumption. The valve has high control sensitivity, safety and reliability, simple debugging and long service life.

Working principle of 900X emergency shut-off valve:
900X emergency shut-off valve is a kind of valve used to allocate the direction of water supply in parallel water supply system of fire water and domestic water. In case of fire, a large amount of water is urgently needed for fire fighting. Domestic water should be cut off immediately to ensure sufficient water for fire fighting; When the fire stop water pressure decreases, the valve will automatically open, in a normally open state, to restore domestic water supply.
Product features of 900X emergency shut-off valve:
1. The valve has high control sensitivity, safety and reliability, simple debugging and long service life.
2. The valve body adopts full channel, direct current and streamline design. The hydraulic loss is small and the energy saving effect is good.
3. 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.
