LK 831 ThermoMix® B
LK 831 ThermoMix® B 4-way bivalent mixing valves are designed for heating systems, where energy is taken from two heating units connected in series or parallel or for storage tank systems where energy is extracted from two levels.
LK 831 ThermoMix® B should be equipped with an automatic control unit to ensure that the most favourable heat source is prioritised at all times.
The valve can be mounted at any angle. Valve ports are marked 1-4. The valve is to be mounted according to 1=Supply, 2=Return, 3=Secondary heat and 4=Primary heat.
