Application
Pr essure 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.
Special Features
• The outlet pressure is set by turning the adjustment knob
1
•G
/4" pressure gauge connections on inlet and outlet
• The adjustment spring is not in contact with the potable water
• The valve insert is of high quality synthetic material and can
be fully exchanged
• Intergral filter
• Easily retrofittable to convert valve to a reverse-rinsing filter
combination
• Inlet pressure balancing - fluctuating inlet pressure does not
influence outlet pressure

D16N Pressure reducing valve with flanged connection
Method of Operation
Spring loaded pressure reducing valves operate by means of a
force equalising system. The force of a diaphragm operates
against the force of an adjustment spring. If the outlet pressure
and therefore diaphragm force fall because water is drawn, the
then greater force of the spring causes the valve to open. The
outlet pressure then increases until the forces between the diaphragm and the spring are equal again.
The inlet pressure has no influence in either opening or closing of
the valve. Because of this, inlet pressure fluctuation does not influence the outlet pressure, thus providing inlet pressure balancing.
