The Caleffi 536 Series PresCal HP is the only direct-acting pressure regulating valve in North America with true piston operation and is now available for ordering. With industry exclusive technology, the 536 Series HP has a piston as the primary control mechanism, instead of a diaphragm. The valve 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. Two models within the 536 Series HP family are available with different pressure adjustment ranges
