Abstract: A sanitary mixing valve assembly, of the single handle type, which includes both a thermostatic control means to preset water temperature, and valving means to regulate volume flow between opened and closed positions, is disclosed. The thermostatic control means and valving means are arranged and constructed to form a unit within a replaceable cartridge.

Abstract: An improved sanitary water faucet having a valve body with control elements formed by two discs wherein the first disc is stationary and has water inlet openings and an outlet opening, connected on one side to the valve manifold. The other side is directed towards the second disc, which is movably arranged on the first disc. The second disc has a surface cavity overlapping the inlet openings, and outlet opening. A noise isolating means preferably consisting of an elastic plate is disposed between the control elements and the valve body. In another embodiment, the isolating means is an elastic valve cartridge disposed in and secured to the valve body and containing the first and second discs. In still a further embodiment, the isolating means is disposed between the discs and the cartridge.
