Caleffi Expands Pressure Regulating Valve Product Range with True Piston Valve Series

The Caleffi 536 Series PresCal HP direct-acting pressure regulating valve with true piston operation and is available for ordering. The series 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 fraught with extreme pressure fluctuations.

Two models are available with different pressure adjustment ranges. The high-range models are rated for inlet pressures up to 360 psi, with an outlet range of 90 to 150 psi. The low-range models are also rated for inlet pressures up to 360 psi, but with an outlet range of 10 to 90 psi.
