Eclipse 300
Thermostatic radiator valve with automatic flow limitation for large radiators and low temperature spreads
The thermostatic radiator valve Eclipse 300 has a unique integrated flow limiter that eliminate over flows. The required flow rate can be adjusted directly at the valve with a twist. 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.
