900X emergent close valve is used in the living and fire fighting merged water supply system. It supplies living water at normal condition and, in case of a fire, automatically close the living water and open the fire fighting one to make it surely enough, and then when fire fighting water stops and the pressure reduced, resets the living water automatically. Thus making the system no need to set an individual fire fighting water supply pipe network and both engineering construction cost and daily water used quantity greatly saved. It features sensitive control, safety, reliability, simple debugging and long duration.
