ABSTRACT:
A valve includes a housing having two inlets and an outlet formed in a bottom panel, a seat secured in the housing and having two ports and an aperture aligned with the inlets and the outlet of the housing. A rotary member is rotatably received in the housing, and engaged onto the seat, and includes a bore communicating with the aperture of the seat, and two slots selectively communicating with the ports of the seat when the rotary member is rotated relative to the housing and the seat. The seat and the rotary member are made of porcelain materials to make a water tight seal without spring members.
