59 LK 841 ThermoMix LK 841 ThermoMix is a 4-way mixing valve suited for heating systems in which a high return temperature is needed to avoid corrosion, thus prolonging the life-time of the heat source. LK 841 ThermoMix is suitable for motorization. LK 841 can be equipped with an insulation - see under Acessories. For more information, please see the product sheet for insulations - page 72. The valve can be mounted at any angle. LK 841 ThermoMix can easily be adapted for right- or lefthand mounting.
