4.5 Equipment to remove excess heat
The two way safety valve DBV 1 - 02 is used for surplus heat removal in case the water temperature
in boiler exceeds 95 °C.
In case the system is equipped with a two- way safety valve DBV 1 – 02 and it comes to the boiler
overheating (the outlet water temperature is above 95 °C) then two-way safety valve will create a cold water
circuit until the temperature drops below the limit temperature. At this moment there is closed the draining
cooling system and the inlet of cold water inlet used for refilling the system.
