Pressure Reducing Valves
Pressure reducing valves of this type 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.
