Emergent-closing valve Characteristic use
900X Emergent-Close Valve is used in the living and fire-fighting emergent water supply system. It supplies living water in the normal conditions. And in case of a fire, close automatically the living water and open the fire-fighting one to make it enough, and when the fire-fighting water stops and the pressure is reduced, resets the living water automatically. Thus making the system no need to set a separate fire-fighting water supply pipeline, this saves both engineering construction cost and daily water quantity used greatly. It features by the sensitive control, safety, reliability, simple debugging and long duration.
