Automatic filling valve for solar (thermosolar) and heating systems with a closed heating circuit

The automatic filling valve is used in heating systems with a closed heating circuit and a pressure range from 1 to 6 bar.
The filling valve is used for automatic filling and restoration of water volume
and maintaining a stable pressure, at a predetermined value, in the system.
The filling valve is equipped with a non-return valve to prevent accidental flow reversal
and mixing the drinking water with the heating fluid.
