ABSTRACT:
A sanitary water valve having control elements consisting of at least two discs. The first disc is arranged immovably and constitutes the valve seat disc and the second disc, which constitutes the control disc, is arranged movably on the first disc and has a surface conduit for deflection functions which can simultaneously be made to overlap the inflow apertures and outflow aperture on the first disc. The second disc includes one or more depressions which substantially reduce the actuation forces required to open the water valve and as a result, operating efficiency is considerably enhanced.
