LK 841 ThermoMix® 2.0 - Female

LK 841 ThermoMix® 2.0 is designed for heating systems where a high return temperature is required to prevent corrosion and thus extend the life length of the heat source.

The valve is suitable for motorization and can be fitted with insulation. For more information, see the insulation data sheet.

A compact design and a octagonal key grip gives an easier access and installation in tight spaces. The valve can be installed in any position and LK 841 ThermoMix® 2.0 can easily be adapted for right- or left-hand mounting.
The valve requires no maintenance but the installation should be
checked regularly.
