With two-point connection for radiators with integrated valves and bathroom radiators, with automatic flow limitation

Multilux V Eclipse is connected in two-pipe systems to radiators with a lower two-point connection such as bathroom radiators, design radiators, universal radiators or radiators with integrated valves. For radiators with integrated valves Multilux V Eclipse is also used as connection fitting without thermostatic head. 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. Thermostatic insert and shut-off insert are interchangeable. Therefore the valve is suitable for installation both left and right side of the radiator.
