Application
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
• 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 outlet pressure gauge
• Inlet pressure balancing - fluctuating inlet pressure does not
influence outlet pressure
• Powder coated inside and outside - Powder used is physiologically and toxicologically safe
• Reliable and proven

D17P 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.
