Pressure reducing valves of this type protect installations against excessive pressure from the supply.
They can be used for household, 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.
