Product Overview
The 900X emergency shut-off valve is a valve used in water supply systems where fire water and domestic water are connected in parallel, to regulate the direction of water supply. When a fire occurs and a large amount of water is urgently needed for firefighting, the 900X emergency shut-off valve immediately cuts off the domestic water supply to ensure sufficient water for firefighting; when the firefighting water stops and the pressure decreases, the valve automatically opens, returning to a normally open state and restoring the domestic water supply. This valve eliminates the need to set up a dedicated separate fire water supply network in the system, greatly saving construction costs and water consumption. The valve features high control sensitivity, safety and reliability, simple debugging, and a long service life.
