A control unit for a hot and cold water mixer that includes one cartridge, one movable disc, one fixed disc, and one valve seat. Within the structure, the first and second openings and the third shell shape opening of the fixed disc will provide the maximum area of water flow in conjunction with the enlarged area of the mixing chamber of the movable disc. The unit will increase the water flow of the valve and will facilitate the transporting capability of a more uniform temperature water. In addition, the cartridge structure may, for any purposes, assemble various connecting pipe lengths or specifications to the valve seat and may form the desired specification as well as reduces the production cost of cartridge molds.
