This 2 1/2 inch threaded pressure reducing control valve with low flow by-pass is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates. Flow requirements below the normal range of the main line pressure reducing control valve are handled by a separate, valve mounted, direct acting, low flow by-pass pressure reducing valve.
