LK 823 Mixing Valve 1¼"


The LK 823 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 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 circuit between the boiler and loading valve. The thermostatic element starts to open port A at an outgoing mixed water temperature in port AB of 65ºC (149ºF). Port B is closed when the temperature in port A exceeds the nominal opening temperature by 10ºC (167ºF).

The valve can be mounted at any angle. LK 823 ThermoVar is for right or left hand mounting.
