with two-point connection, angle and straight type, for R 1/2 and G 3/4 connection, with automatic flow limitation

The Multilux 4-Eclipse-Set is connected in 2-pipe systems to radiators with a lower 2-point connection such as bathroom radiators, design radiators, universal radiators or radiators with integrated valves. The valve has a unique integrated flow limiter that eliminates over flows. The required flow rate can be adjusted with one twist directly at the valve. The adjusted flow will not be exceed even if there are load changes in the system, due to other valves closing or during morning start up. The valve controls the flow rate independently from differential pressure. Therefore, complicated calculations to determine settings are not necessary. Centre-to-centre distance of connections 50 mm. The Multilux 4-Eclipse-Set is suitable for installation as angle or straight form. Thermostatic insert and shut-off insert are interchangeable. Therefore the valve is suitable for installation both left and right side of the radiator.
