HOT WATER RECIRCULATION VALVE

摘要

A valve for use in a water circulation system having a source of unheated water and a source of heated water, said valve comprising: a housing defining a heated water input, an unheated water input and an output; a valve stem supported within said housing defining a primary flow passage, an output passage in fluid communication with said primary flow passage and a bypass flow passage; a handle constructed to facilitate movement of said valve stem between an off position, an on position and a bypass position, wherein said on position has said valve stem positioned within said housing such that said primary flow passage provides water flow from said heated water input and said unheated water input to said output passage and said bypass passage is blocked and wherein said off position has said primary flow passage and said bypass passage blocked and wherein said bypass position has said bypass flow passage couples said heated water input to said unheated water input and said primary flow passage is blocked.
