LK 551 HydroMix is an asymmetrical mixing valve for water

heating and heating systems. The mixing valve has a thermo-

static element that regulates the supply of cold as well as hot

water in order to achieve the desired temperature. The valve has

an anti-scald function that shuts off the incoming hot water flow

in case of failure of cold water supply.

Arrows on the valve body indicate the direction of the flow.

C = incoming cold water

H = incoming hot water

M = outgoing mixed water
