MÔ TẢ SẢN PHẨM :

Pressure reducing valve with flange connection
Standard pattern

VAN GIẢM ÁP

Construction
The pressure reducing valve comprises:
• Housing with PN25 flanges to DIN 86021
• Valve insert complete with diaphragm and valve seat
• Spring bonnet with adjustment knob
• Filter with 0.5 mm mesh
• Filter bowl
• Adjustment spring
• Pressure gauge not included (see accessories)
Materials
• Red bronze housing
• High-quality synthetic material valve insert
• Brass spring bonnet
• Stainless steel filter mesh
• Brass filter bowl
• Spring steel adjustment spring
• Fibre-reinforced NBR diaphragm
• NBR seals
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
• The outlet pressure is set by turning the adjustment knob
• G1/4″ pressure gauge connections on inlet and outlet
• 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
• Intergral filter
• Easily retrofittable to convert valve to a reverse-rinsing filter
combination
• Inlet pressure balancing – fluctuating inlet pressure does not
influence outlet pressure
Range of Application
Technical Data
Medium Water, compressed air* and nitrogen* in
consideration of valid standards (e.g. DIN
EN 12502)
Inlet pressure max. 25 bar
Outlet pressure 1.5-12 bar
Set during manufacture at 4.0 bar outlet pressure
Operating temperature
max. 70°C
Nominal pressure PN25
Minimum pressure
drop
1 bar
Nominal size DN15 – DN40
* As part of an installation being approved according to PED requirements, this product must also be certified.
EN0H-1005

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.
