​​​​​​​ 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.

Integrated flow limiter

Eliminates over flows

Easy adjustment

Just a twist to reach design flow

Flow range from 30 to 300 l/h

For high flexibility

Perfect for renovation

Standard dimensions and easy flow sizing
