green dot for potable water
The model is available in the following dimensions: d 16 / 20 / 25.
Press connection with SC-Contur
SC‑Contur
Viega press connections 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 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:
with wet leakage test in the pressure range from 0.1 hPa–0.65 MPa (1.0 mbar–6.5 bar)
with dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar)
Markings on components
The press connections are marked with a coloured dot. This identifies the SC‑Contur, where the test medium would escape in the case of an inadvertently unpressed connection.
The model is marked as follows:
flow direction indicator
noise class I on the basis of applicable regulations, see Regulations from section: Marking on components
