<strong>LK</strong> 841 ThermoMix is a 4-way mixing valve suited for<br />
heating systems in which a high return temperature is<br />
needed to avoid corrosion, thus prolonging the life-time<br />
of the heat source.<br />
<strong>LK</strong> 841 ThermoMix is suitable for motorization.<br />
The valve can be mounted at any angle. <strong>LK</strong> 841 ThermoMix<br />
can easily be adapted for right- or left-hand mounting.<br />
