CAPACITY DIAGRAM

LK 552 HydroMix is a mixing valve for water heating and heating

systems. The mixing valve has a thermostatic element that reg-

ulates 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
