Application

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.

Description

Circulation regulation valve (CRV) fittings, suitable for various fields of application.

Features and benefits:

  • One valve with two functions.
  • 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 - installation is also possible in both the riser pipe and on the storey.
  • 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.
  • Temperature range of 40–65°C.
  • Helps to provide constant water temperatures at every extraction point.
  • Opens and closes automatically to regulate the flow volume depending on the water temperature in the circulation pipe.
  • Can be used with all types of drinking water.
  • Integrated into the installation easily and quickly using press connections of 15 mm, 18 mm, or 22 mm, or screw fittings in G ¾ and G 1 with plastic piping systems.
  • The control unit of the circulation regulation valve is equipped with a flexible material element which reacts to temperature changes of the hot water in the circulation circle. If the set value differs from the actual temperature, the flow-through volume is changed by means of the valve lift to regulate the water temperature.
  • The signal colour of the position indication shows whether a valve is open or closed, even when seen from a distance.
  • Innovative sealing concept 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).

Applications:

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.
