Diaphragm-actuated pressure reducing valve
with cartridge insert


The pressure reducing valve comprises:
• Housing with PN16 flanges per ISO7005-2, EN1092-2
• Spring bonnet with adjustment screw
• Adjustment spring
• Cartridge insert
• Pressure gauge
• Housing made of ductile cast iron (EN-GJS-400-15 EN1563),
coated with PA (polyamide)
• Spring bonnet made of ductile cast iron (EN-GJS-400-15
EN1563), coated with PA (polyamide)
• Cartridge insert made completely of low-lead (<2.2% acc. to
DIN 50930 part 6) brass with stainless steel valve spindle
• Spring steel adjustment spring
• Diaphragm and seals made of EPDM
• Groove ring and sealing disc made of high-quality PU
• Stainless steel screws and nuts

Pressure 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
• DVGW-, WRAS- and ACS-certified for all connection sizes
• Patented cartridge solution for easy assembly and maintenance
• One cartridge insert fits all nominal widths, making warehousing efficient
• Meets all requirements of DIN EN 1567
• None of the materials used exceed the permissible limits for
lead content specified by DIN 50930 Part 6
• Functionality and performance have been confirmed by an
accelerated life test with over 400,000 cycles (requirement
acc. to DIN EN 1567: 200,000 cycles)
• Meets KTW recommendations for potable water
Range of Application
Technical Data
Medium Drinking water
Inlet pressure max. 16 bar
Outlet pressure 1.5 – 6.5 bar
Operating temperature max. 65°C
Nominal pressure PN16
Minimum pressure drop 1.0 bar
Nominal size DN65, DN80, DN100

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.
