Description
LK 823 ThermoVar® R 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 increasing the efficiency of the system. Tarring and condensation are prevented which prolongs boiler life.
The valve regulates on two ports, which means that there is no need for a balancing valve in the cirucit between boiler and loading valve. The thermostatic element starts to open port A when the outgoing mixed water temperature in port AB reaches the opening temperature. Port B is closed when the temperature in port A exceeds the nominal opening temperature by 10 °C.
The valve is adjustable within the range of 55 °C to 70 °C.
LK 823 R 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 823 ThermoVar® R is for right- or left-hand mounting.
