Pressure reducing valve with balanced seat
Low pressure pattern


The pressure reducing valve comprises:
• Housing with PN16 flanges per ISO7005-2, EN1092-2
• Spring bonnet with adjustment screw
• Adjustment spring
• Valve system complete with diaphragm
• Pressure gauge
• Grey cast iron housing
• Cast iron spring bonnet
• Bronze valve seat
• Bronze piston guide
• Cone up to DN150: brass, DN200: steal
• Spring steel adjustment spring
• EPDM diaphragm
• NBR seal collar
• NBR seals
• Stainless steel screws and nuts
Pressure reducing valves of this type protect installations against
excessive pressure from the supply. They can 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
• Non-rising stem for setting outlet pressure and position indicator on spring bonnet (except for DN200)
• The adjustment spring is not in contact with the potable water
• With inlet and outlet pressure gauge (DN80-DN150) or with
outlet pressure gauge (DN50, DN65, DN200)
• Inlet pressure balancing – fluctuating inlet pressure does not
influence outlet pressure
• Powder coated inside and outside – Powder used is physiologically and toxicologically safe
Range of Application
Technical Data
Medium Water, compressed air* and nitrogen* in
consideration of valid standards (e.g. DIN
EN 12502)
Inlet pressure max. 16 bar
Outlet pressure 0.2 – 2 bar
Operating temperature
max. 70°C
Nominal pressure PN16
Minimum pressure
0.5 bar
Diaphragm pressure
max. 3.0 bar
Nominal size DN50 – DN200
* As part of an installation being approved according to PED requirements, this product must also be certified.

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.
