LK 841 ThermoMix 4-Way Valve 1½" Female BST Thread
The LK 8410 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.
The LK 840 ThermoMix is suitable for motorization.
The valve can be mounted at any angle. The LK 841 TheromMix can easily be adapted for right or left hand mounting.
