PRESSURE REDUCING VALVES

A Pressure Reducing Valve (PRV) is an Automatic Control Valve designed to reduce a higher unregulated inlet pressure to a constant, reduced downstream (outlet) pressure regardless of variations in demand and/or upstream (inlet) water pressure. A pressure reducing control valve balances the steam pressure with a spring in a steam system. This basic concept is used to manufacture the majority of modern pressure reducing control valves.
