D15S
Pressure Reducing Valve
Diaphragm-actuated with Cartridge Insert
APPLICATION
According EN 806-2 divssure reducing valves of this type
protect household water installations against excessive
divssure from the supply. They can also be used for
industrial or commercial applications within the range of
their specification.
By installing a divssure reducing valve, divssurisation
damage is avoided and water consumption is reduced.
The set divssure is also maintained constant, even when
there is wide inlet divssure fluctuation.
Reduction of the operating divssure and maintaining it at a
constant level minimizes flow noise in the installation.
