Press connection with SC-Contur
Fig. 1: SC-Contur
Easytop ball valve with SC-Contur 9 from 19
Page 10
Viega press connections are equipped with the SC-Contur. The SCContur is a safety technology that is certified by the DVGW and ensures
that the connection is guaranteed to be leaky in an unpressed state. In
this way, unpressed connections are noticed immediately during a
leakage test.
Viega guarantees that unpressed connections are visible during a
leakage test:
n with wet leakage test in the pressure range from 0.1 hPa–0.65 MPa
(1.0 mbar–6.5 bar)
n with dry leakage test in the pressure range from 22 hPa–0.3 MPa
(22 mbar–3.0 bar)
2.3.3 Sealing elements
Area of use of the EPDM sealing element
Product information
NOTICE!
Only EPDM sealing elements are approved in potable water
installations. The use of other sealing elements is not per‐
mitted.
The model is factory-fitted with EPDM sealing elements.

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