Viega Hygiene function

Press-​in nozzles
Intended operation supported by water exchange in branched ring systems in accordance with the Venturi principle.
For rarely used piping sections, such as supply pipes to heating filling stations, sink basins and external extraction fittings up to a length of 15 m and max. 5 draw-​off points.
For T-​pieces of Profipress, Sanpress, and Sanpress Inox systems with branch d15 in customised dimensioned supply lines.

Smartloop inliner technology
Allows allows economic installation and energy-​efficient operation of a hot water riser pipe circulation.
As an internal circulation pipe for riser pipes from d28 to d108.0 of the Profipress, Sanpress and Sanpress Inox systems.

Circulation regulation valves
Thermostatic regulation valves for the hydraulic line or storey calibration, casing and water contacting parts made of gunmetal or silicon bronze, control range 40 to 65 °C, blockable, with drain plug.
Static regulation valve for the hydraulic circuit balancing, casing and water contacting parts made of gunmetal.

Press connector with SC‑Contur
Inadvertently unpressed connections become visibly leaky when the system is filled.
Viega guarantees the detection of unpressed connections in the following pressure ranges:
min. water pressure: 0.1 MPa / 1 bar / 14.5 PSI
max. water pressure: 0.65 MPa / 6.5 bar / 94.3 PSI
min. air pressure: 22 hPa / 22 mbar / 0.3 PSI
max. air pressure: 0.3 MPa / 3 bar / 43.5 PSI

Sealing elements
EPDM (ethylene propylene diene rubber), black, pre-​assembled

Dimensions
