Application
The pressure reducing valve combination combines a shutoff
valve, a pressure reducing valve and a double check valve in one
appliance.
This all-in-one device saves space and simplifies the installation.
The combination protects household water installations against
excessive pressure from the supply. The assembly can also be
used for industrial or commercial applications within the range of
its 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.
The double check valve protects the mains water system against
back pressure, back flow and back syphonage of health threatening liquids.
Special Features
• WRAS-approval requested (Pressure reducing valve and
double check valve)
• Especially compact because shutoff valve, pressure reducing
valve and double check valve are combined in one unit
• 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
• Inlet pressure balancing - fluctuating inlet pressure does not
influence outlet pressure
• Meets KTW recommendations for potable water

Method of Operation
The pressure reducing combination combines a shutoff valve, a
pressure reducing valve and a check valve in one appliance.
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.
Check valves have a moving seal disc which is lifted off the seat
by a greater or lesser amount depending on the flow rate through
the valve. If the flow falls towards zero, then the spring pushes
the disc back onto the seat and seals the waterway.
