Load valve

VTC500

  • Accurate control of the return water temperature.
  • Easy installation. No need of adjustment valve.
  • Easy but normally not required maintenance.
The series VTC500 is a thermic valve used for solid fuel boilers up to 150 kW. The load valve makes sure that the boiler gets up to a high combustion temperature so as to ensure the lowest possible emissions. Above all, the valves make sure that the return temperature to the boiler is kept high and guaranteed over the entire combustion cycle which enables a higher level of boiler efficiency, reduced tarring and increased life span of the boiler.
