Emergency shutoff valve
The emergency shut-off valve is mainly composed of a main valve 2, a check valve 5, a needle valve 1 and a ball valve 3, a pressure valve table 4 and the like. The emergency shut-off valve is used in the parallel water supply system of the fire-fighting water area in the living area. When fire water is used, the valve automatically shuts down domestic water and fire water. When the fire is over, the valve opens automatically to restore the living water supply. It is more cost-effective than traditional firefighting alone.
