QV900X emergency shut-off valve

Function and Application:
This valve is used in the water supply system for parallel connection of fire water and domestic water in residential areas. When using fire water, the valve automatically closes urgently, cutting off domestic water to ensure fire water supply. When the fire is over, the valve automatically opens, and restoring domestic water supply can save costs more than traditional separate fire water supply.
