Easytop system fittings


Shutdown and control valves made of stainless steel, gunmetal or silicon bronze for potable water and heating installations with DVGW test mark. Combinable with Viega systems Sanpress Inox, Sanpress, Profipress, Prestabo, Raxofix and Sanfix P in the Viega system group.

Easytop system fittings with press connections
All sizes with SC‑Contur – accidently unpressed connections become visible during filling the system. The SC‑Contur is certified and fulfils the requirements of the DVGW worksheet W 534, point 12.14, Connectors with forced leakage.
During leakage tests with water Viega guarantees the identification of unpressed connections in the pressure range 0.1 MPa–0.65 MPa, in the case of dry leakage tests with compressed air or noble gases from 22 hPa–0.3 MPa.

    The use of the system for other than those described areas of application and media must be approved by the Viega Service Center.

    Operating conditions
    The permitted operating temperatures and pressures of the products can be found in the instructions for use.
    Observe flow direction!
    Components made of copper may not be installed upstream from galvanised ferrous materials.

    Use of press tools
    The functional safety of the Viega press connector systems primarily depends on the perfect condition of the press tools and press machines used. For this reason, for the production of press connections we recommend the use of Viega press tools and their regular inspection by authorised service points.
