Abstract
For purposes of the stop of flow of water and the reduction of excess pressure in potable or sanitary water supply pipe lines, a Combination Stop and Pressure Reducing valve having one bonnet only. This combination valve, of the same size as the conventional stop valve now used in the plumbing industry, replaces the stop valve at its commonly used location and, simultaneously replaces the pressure reducing valve which is generally installed elsewhere in the pipe lines. A stop cock version is provided in which the pressure reducing assembly is contained within the valve bonnet which is, in turn, secured to the valve body for opening and closing by rotatable or longitudinal displacement of the bonnet.
