LK 840 ThermoMix C is a motorized 3-way valve that can be used as a mixing valve or as a diverting valve in heating systems.

Actuator LK 940 ThermoMix C shall be used on LK 840 ThermoMix C. Assembly/disassembly of actuator on LK 840 ThermoMix C is simple and secure, using the clip-system.

Depending on model the actuator can be operated by a controller with a 3-point SPDT output or a proportional
0-10 V / 4-20 mA output. The angle of rotation is electrically limited to 90°.
When needed, the actuator can be put into manual mode by pressing the button on the housing cover. The actuator can now be put in any position by turning the handle on the front. The position is indicated on the reversible scale.
