Application
D03 pressure reducing valves protect householdwater
installations against excessivepressure from the supply.
They can also be used for industrial or commercial
applicationswithin the rangeof their specification.
By installing a pressure reducing valve, pressurisation
damage is avoided andwater consumption is reduced. The
set pressure is alsomaintained constant, evenwhen there is
wide inlet pressure fluctuation.
Reduction of the operating pressure andmaintaining it at a
constant level minimizes flownoise in the installation.
