Components can be used for residential buildings, but also for installations in industrial applications such as plant engineering and shipbuilding, as well as:

  • Drinking water installations.
  • Heating.
  • Compressed air or technical gases.

Components can be used as maintenance fittings, for shutting off individual devices, riser pipes, or entire story connection pipes. Consult manufacturer for further details.


Concealed free-flow valve fittings, suitable for various fields of application.

Features and benefits:

  • Suitable for shutting off storey or apartment units.
  • High performance in terms of safety and functionality due to SC-Contur and optimized sealing.
  • Designed to fulfil all requirements.
  • There is no need for sealed transitions.
  • Easy to install in confined installation situations.
  • Manufactured from corrosion resistant stainless steel or gunmetal.
  • Plastic T-shaped levers, metal T-shaped levers or metal L-shaped levers can be used dependent on application conditions.
  • Covers instant pressing and conventional screwed connections.
  • Economically efficient.
  • Easytop mounting units are available - consult manufacturer for details.
  • Meets the specifications of the DVGW Worksheet W270.
  • Maintenance free top without dead spaces, equipped with a shut-off unit/ water-contact surface manufactured from EPDM.
  • Can be used with drinking water of all types.
  • It is available in sizes DN 15 and DN 20 and can be retrofitted with a self-adhesive insulating shell made of EPP insulating material.
  • Suitable for front mounting via the wall lead-in of the protective sleeve, or for rear mounting through a wall bracket which is screwed to the valve.
  • Damage to the joints and tiles during final mounting is avoided due to the permanent protective sleeve.
  • Can be installed in conventional masonry dry and wet walls, independent of the flow direction.
  • Permits a variable installation depth of 43–130 mm.
  • A quarter-turn is sufficient to close or open the valve completely, which provides short operating distances.
  • Covers the full cross section, keeping the pressure losses to a minimum.
  • The one piece shut-off cylinder with EPDM coating and integrally moulded spindle is identical for all valve sizes and is easy to replace if necessary.
  • The signal colour of the position indication shows whether a valve is open or closed, even when seen from a distance.
  • Innovative sealing concept of the system valves protects the valve plate seal from damage caused by excessive pressing forces.
  • Handwheels are easy to grip.
  • Matches Viega's metal and plastic press connector systems, and can be combined with Sanpress, Sanpress Inox or Profipress.
  • Different parts of the system comply with standards such as DIN EN 1213:1999, DIN 50930-6, DIN EN 1982, DIN EN 13828 and DIN EN 1092-1.
  • DVGW CERT GmbH approved.

Central leakage test:

Equipped with the Viega SC-Contur, which is a safety technology approved by Kitemark, and ensures that the connection is guaranteed to be leaking in an unpressed state. In this way, inadvertently unpressed connections are noticed immediately during a leakage test.

Viega guarantees that unpressed connections are visible during a leakage test:

  • With the wet leakage test in the pressure range from 0.1–0.65 MPa (1.0–6.5 bar).
  • With dry leakage test in the pressure range from 22 hPa–0.3 MPa (22 mbar–3.0 bar).
