1900XEmergency shutdown valve overview

900XEmergency shut-off valve is a valve used in a water supply system that connects fire water and domestic water in parallel, to adjust the direction of water supply. When a fire occurs, the fire department urgently needs a large amount of water and immediately cuts off domestic water to ensure sufficient fire water supply; When the water pressure decreases after the fire stops, the valve automatically opens and returns to a normally open state, restoring domestic water supply. This valve eliminates the need for a dedicated fire water supply network in the system, greatly saving construction costs and water consumption. Valve control has high sensitivity, safety and reliability, easy debugging, and long service life.

II900XMain purpose of emergency shut-off valve

900XEmergency shut-off valves are used in parallel water supply systems for both domestic and firefighting purposes. Under normal circumstances, they provide water for domestic use. In the event of a fire, the valves automatically close the domestic water supply to ensure sufficient firefighting water supply. When the fire department stops using water, the pressure decreases and the valve automatically restores domestic water. This valve eliminates the need for a dedicated fire water supply network, greatly saving construction costs and daily water consumption. This valve is sensitive in control, safe and reliable, easy to debug, and has a long service life.
