The pressure reducing valve combinations combine a shutoff valve, a pressure reducing valve and a
double check valve in one appliance. They protect household water installations against excessive
pressure from the supply. They can also be used for industrial or commercial applications within the
range of their specification. By installing a pressure reducing valve, pressurisation damage is avoided
and water consumption is reduced. The set pressure is also maintained constant, even when there is
wide inlet pressure fluctuation. Reduction of the operating pressure and maintaining it at a constant
level minimizes flow noise in the installation. The double check valve protects the mains water system
against back pressure, back flow and back syphonage of health threatening liquids.
