LK 830 ThermoMix® B 4-way bivalent mixing valves are de-

signed 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 830 ThermoMix® B should be equipped with an automatic

control unit to ensure that the most favourable heat source is

prioritised at all times.

LK 830 ThermoMix® B can be adapted for right- or left-hand

installation.
