Function
C34 3-way mixing valve with bypass 0-50%
The flow temperature of the heating circuit is
controlled by the integrated mixing valve.
Heated or cooled water from the boiler and cooled
or heated return water are mixed to obtain the
desired flow temperature of the heating circuit.
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 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 significantly
different flow temperature than the
one provided by the boiler
•
Consumer circuits with high flow rates,
f.ex. radiant floor heating and radiant
panel heating systems
