Radiators, Trench Heaters, Radiant Panels

Provides optimal ambient temperature through two dynamic control elements, which automatically balance the heating system irrespective of how many valves are exercised within the system. The proven capsule control diaphragm and the inlet pressure sensor in the Vario DP valve insert control the flow rate. The sensor in the thermostatic head controls the optimal room temperature. The patented, dynamic valve insert automatically limits and maintains the flow rate of water, independent of pressure fluctuations in the heating system. Also prevents potential water contamination within the system settling in the valve. Automatic system balancing is quick and easy due to the tamper proof flow rate setting, which regulates the water flow with 100% authority. The unique design of the valve as well as the wide range of settings enables universal, flexible application with high accuracy at all times, with maximum protection against contamination.
