LK 820 ThermoVar® is a 3-way thermic loading valve for solid fuel/storage tank installations. The valve is intended to ensure both an optimal temperature stratification in the storage tank and a high return temperature to the boiler, thus incresasing the efficiency of the system. Tarring and condensation are prevented which prolongs boiler life. LK 820 can be equipped with an insulation – see under Accessories. For more information, please see the product sheet for insulations. The valve can be mounted at any angle. LK 820 ThermoVar® can easily be adapted for right- or left-hand mounting. The valve can be installed in three different positions. In the standard version the valve is intended for installation in position II. It can easily be adapted for installation in position I.
