Backflow preventer

2.3.2

Markings on components

The model is fitted with a backflow preventer.

Backflow preventers only allow flowthrough in one direction (in the
direction of flow). If the direction of flow changes, e.g. due to back suc‐
tion, the backflow preventers close automatically.

The model is available in the following dimensions: DN 50 / 65 / 80 / 100

The model is marked as follows:

n flow direction indicator
n dimension
n DVGW writing
n position indicator below the handwheel, with CRV writing
n EA marking for classification in accordance with the applicable regu‐

lations, see Ä „Regulations from section: Marking on compo‐

nents“ on page 7

2.3.4 Operating mode

Combined backflow preventer (CBP)

Backflow preventers protect fittings and installation systems against
unintended backflow, back pressure or back suction of the contami‐
nated wastewater or dirty water in the piping system. This can occur
after pressure fluctuations in the distributor circuit, which can cause a
change in the direction of flow.

The backflow preventer prevents the pushing back, backflow or back
suction of liquids, which may be a health hazard, into the public drinking
water network, with the help of a spring-loaded valve cone. The dimen‐
sion is dependent on the peak pressure and it complies with the nom‐
inal width of the pipeline. The backflow preventer must be fitted with
testing equipment.

Product information

2.3.5

Technical data

In many countries, standards and technical guidelines stipulate the use
of backflow preventers or other suitable safety equipment that protect
drinking water against contamination.

Observe the following operating conditions for the installation of the
model:

Operating temperature [T

Operating pressure [P

] 90 °C

max

] 1.6 MPa (16 bar)

The performance diagram shows the pressure losses (in hPa) in relation
to the volume flow and the nominal width.

2.4 Information for use

2.4.1 Corrosion

Product information

Overground pipelines and fittings in rooms do not normally require
external corrosion protection.

There are exceptions in the following cases:

n Contact with aggressive building materials such as nitrite or mate‐

rials containing ammonium

n in aggressive surroundings

If external corrosion protection is required, observe the pertinent guide‐
lines, see Ä „Regulations from section: Corrosion“ on page 7.

Easytop fittings made of gunmetal/silicon bronze are suit‐
able for all types of potable water.

The chloride concentration in the medium must not exceed
a maximum value of 250 mg/l.

2.5 Optional accessories

This chloride is not a disinfectant, but in fact pertains to the
content in sea and table salt (sodium chloride).

The following optional accessories are available:

n Drainage valves
n Mounting sets
n Seals

3.4

Disposal

Observe the applicable regulations for the operation and maintenance
of drinking water installations, see Ä „Regulations from section: Mainte‐

nance“ on page 8.
