3.2 Function
K34 3-way mixing valve with bypass 0-50 %
The flow temperature of the heating circuit is
controlled by the integrated mixing valve. Hot water
from the boiler and cold return water are mixed to
obtain the desired flow temperature. The mixing
valve is adjusted via an external controller in
combination with the electric actuator.
Due to the premixing rate that must be adjusted
at the bypass of the mixing valve, a certain amount
of cold return water is added to the flow water.
The 3-way actuator can thus work over the whole
adjustment range (0-100%), although only a small
amount of water from the boiler is necessary.
Example: Radiant panel heating systems operate
on a low temperature level with small temperature
differences but with high flow rates. It is therefore
sufficient to "inject" a small amount of hot water
into the "warm" return water.
Application range:

Consumer circuits with a considerably
lower flow temperature than the boiler
flow temperature
 Consumer circuits with high flow rates,
f.ex. radiant floor heating and radiant
panel heating systems
