Easytop Valves (Circulation Regulation Valve)

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 / silicon bronze.
• 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.
• Easytop mounting units are available - consult manufacturer for details.
• Operating Max Temperature 80°C.
• Control range 40°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).
