VALVE CHARACTERISTICS

CAPACITY DIAGRAM

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 ac-

cess and installation in tight spaces. The valve can be installed

in any position and LK 841 ThermoMix® 2.0 can easily be adapt-

ed for right- or left-hand mounting.
