Markings on components
Easytop ball valve with SC-Contur
Viega press connectors are equipped with the SC-Contur. The SC-
Contur is a safety technology that is certified by the DVGW and ensures
that the connection is guaranteed to leak 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:
with wet leakage test in the pressure range from 0.1 hPa–0.65 MPa
n
(1.0 mbar–6.5 bar)
with dry leakage test in the pressure range from 22 hPa–0.3 MPa
n
(22 mbar–3.0 bar)
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.
