The PresCal HP family ensures stable, high-precision water pressure control while withstanding severe inlet pressure or punishing downstream water hammer. It’s perfect for staged pressure control or demanding applications that are fraught with extreme pressure fluctuations. The high-range model serves as a first-stage PRV in a two-stage application. The low-range model serves as a second stage, or as a stand-alone PRV for punishing pressure spikes. Booth #B3317.
