VEXVE ALV 3231 45°C DN40 1 1/2" external thread

VEXVE Three-way thermostatic loading valve ALV 3231 45°C DN40 1 1/2"

Versions with internal and external threads. The arrow on the valve cover indicates the opening closed by the thermal valve. In the ALV valve, the opposite opening is not closed. At the beginning of the boiler heating process, the thermal valve (diagram 1) is closed and water circulates through the boiler bypass. After reaching the valve opening temperature (thermal element characteristic), the paraffin thermoelement expands and its tip opens the valve shut-off disc, thus slightly opening the return flow from the heat accumulator to the boiler. When the thermoelement is fully heated, to a temperature 12°C higher than the opening temperature, both the water circulation through the boiler bypass and from the heat accumulator remain open in the ALV valve. Consequently, water distribution through both circulations
