Реферат: A recirculation valve includes a housing including a hot water fluid passage which is used to allow the hot water to flow through, a cold water fluid passage to allow the cold water to flow through, and a recirculation fluid passage to allow the hot water in the hot water fluid passage to flow into the cold water fluid passage, a water pressure plate provided to close the recirculation fluid passage when the cold water or the hot water is used, and to open the recirculation fluid passage when the cold and hot waters are not used, and a bimetal plate configured to open the recirculation fluid passage as the bimetal plate is spaced apart from a recirculation opening and to close the recirculation fluid passage by making contact with the recirculation opening, and positioned downstream of the recirculation opening in a direction in which the hot water flows.
