Backflow Preventers
BA300
Backflow Preventer
with flanged connections
APPLICATION
Backflow preventers of this type are suitable for the
protection of drinking water systems against back pressure,
back flow and back syphonage.
Fluids up to and including liquid category 4 to EN 1717 are
protected.
They can be used for residential buildings, industrial and
commercial purposes within the scope of their specification.
The powder-coated ductile iron housing provides increased
corrosion protection.

CONSTRUCTION
METHOD OF OPERATION
BA type backflow preventers are divided into three pressure
zones. The pressure in zoneis higher than in zone ,
which in turn is higher than in zone . A discharge valve is
connected to zone which opens at the latest when the
differential pressure between zones and drops to
0.14 bar. The water from zone discharges to atmosphere,
both check valves close and therefore separate zone from
zone and . In this way the danger of back pressure or
back syphonage into the supply network is prevented. The
pipework connection is interrupted and the drinking water
network is protected.
TRANSPORTATION AND STORAGE
Keep parts in their original packaging and unpack them
shortly before use.
The following parameters apply during transportation and
storage:
*non condensing
INSTALLATION GUIDELINES
Setup requirements
•Install shut-off valves before and after backflow
preventer
•Install backflow preventer downstream of the filter or
strainer
–This protects the appliance against dirt
•Install in horizontal pipework with the discharge valve
downwards
•Ensure good access
–Simplifies maintenance and inspection
•In order to avoid flooding, it is recommended to arrange
a permanent, professionally dimensioned wastewater
connection
•The installation environment should be protected
against frost and ventilated well
•Install discharge pipework which has adequate capacity
•These armatures need to be maintained regularly
