Description of function
K36E - DN 25 (1")
The K36E should always be used with a
buffer tank, if not, a hydraulic separator is
mandatory.
Thermal control valve with bypass
Function:
The thermal valve shuts off the connection to the consumers, as long as the water in the boiler
circuit is colder than the opening temperature of the thermal control valve.
The pump in the K36E circulates the water in the boiler circuit by means of the automatic
bypass which is completely open.
When the water in the boiler circuit has obtained the opening temperature (+/- 3 K) of the
thermal control valve, the valve opens the connection from/to the consumers.
The bypass shuts off to the same extent as the connection to the consumers is opened.
The control valve opens the return from the consumers and enables thus a circulation in the
consumer circuit. The cold water from the consumer return line is mixed with the hot water
from the bypass at the control valve. Depending on the temperature and the flow rate of the
water from the return line, the thermal control valve shuts or opens the line to the consumers.
Thus, the return to the boiler always remains at a certain temperature level.
With rising temperature in the flow line of the boiler or with rising temperature from the return
line of the consumers, the thermal control valve opens the connection to the consumers.
During operation, the temperature of the return of the boiler remains nearly constant (+/ -3 K).
Please note: When the boiler output is controlled by the boiler temperature the boiler must
heat up 20 K above the opening temperature of the K36E. Otherwise there will not be enough
power available for the consumers (the boiler output may be reduced before the thermal
control valve opens completely).
