Application
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.
Special Features
• DVGW-approved for connection sizes 1/2" - 1"
• NF EN 1567 approved (only D05F-…EF versions)
• The outlet pressure is set by turning the adjustment knob
• The set pressure is directly indicated on the set point scale
• 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
• Integral fine filter
• Also available without fittings
• Inlet pressure balancing - fluctuating inlet pressure does not
influence outlet pressure
• Light weight
• Meets KTW recommendations for potable water

D05F Pressure reducing valve with balanced seat
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.

Installation Guidelines
• Install in horizontal pipework with spring bonnet directed
upwards
• Install shutoff valves
• The installation location should be protected against frost
and be easily accessible
o Pressure gauge can be read off easily (see accessories)
o Simplified maintenance and cleaning
• For residential applications where maximum protection
against dirt is required, install a fine filter upstream of the
pressure reducing valve
• Provide a straight section of pipework of at least five times the
nominal valve size after the pressure reducing valve (in accordance with DIN 1988, Part 5)

Typical Applications
Pressure reducing valves of this type are suitable for all types of
household water installations.
Pressure reducing valves can also be used for industrial and
commercial applications within the range of their specifications.
Pressure reducing valves should be installed:
• If the static pressure exceeds the maximum permissible value
for the system
• As protection against noise if the static pressure at take off
points exceeds 5.0 bar (DIN 4109: Noise protection in high
buildings)
• If several pressure zones are required when a pressurisation
system is used (pressure reducers on each storey of a building)
• If pressure fluctuations in the downstream system must be
avoided
• To achieve constant inlet and outlet pressures on pumped
pressure boosting systems
