Easytop Valves (Concealed Free-Flow Valve)

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).
