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
