Pressure Reducing Valve
Also called water pressure regulators, water pressure reducing valves are compact, inexpensive 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.
