An improved 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 toward 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 of the first disc. Noise-reducing assembly including a plurality of overlapping screens, the wire orientation of each screen being angularly offset with respect to that of the other screens, the assembly being disposed within the surface cavity of the second disc with the wire screens spaced from the ceiling thereof to form a chamber which aids in reducing the cavitation noise of the valve.
