K34R: 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 of
the heating circuit. The mixing valve is adjusted by
means of the weather compensated controller
PWR6.
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:
Panel heating systems operate on a low temperature
level with small temperature differences, but with
high flow rates.
It is therefore sufficient to add a small amount of hot
water to the "warm" return water.
For the use as a return flow temperature
maintenance, the bypass in the mixing valve must be
completely closed so that the entire boiler output is
available for the consumer circuits.
