Abstract

A domestic water supply shutoff valve for use with fire protection system water supply piping has a body defining a volume for flow of water through the valve, with a supply inlet for connection to a supply of water, a first outlet for connection to fire protection system water supply piping, and a second outlet for connection to domestic system supply piping. A first passageway is defined within the body for flow of water from the supply inlet toward the first outlet. A second passageway is defined within the body for flow of water from the supply inlet toward the second outlet. A poppet valve is disposed within the body and mounted for movement between a first position for permitting flow of water from the inlet toward the first outlet and a second position for permitting flow of water from the inlet toward the second outlet, the poppet valve being biased toward the second position.
