A mixing valve 10 has a cartridge assembly 20 therein which has stationary plate 22 having hot and cold openings 24 and 26 and a movable plate 28 slidably mounted thereupon. The movable plate has a surface 29 abutting plate 22 free from apertures. Valve plate 28 moves translationally between an open and closed position and rotated between a cold and hot position. The valve plate can be rotated through approximately 180 degrees with a tooth 66 of plate 28 leveling the mixing profile at the comfort zone between the hot and cold positions (FIG. 1). The valve plate 28 is controlled by a drive lever that can be either rotated about a vertical axis or moved in a vertical plane.
