Art. 749 DN32
Function
The anti-condensation thermic valve optimizes the connection of the solid fuel heating source to the heating system, or to the puffer, automatically adjusting the temperature of the water returning to the generator to the calibration value of the chosen thermostat.
The device keeps the heat generator at a high temperature (always above that of condensation) in any condition of use, avoiding the formation of sediments both in the boiler and in the chimney flue, thus improving its efficiency and life. Corrosion of the heat generator or dangerous chimney flue fires are therefore avoided.
Technical features
Anti-condensation thermic valve with thermostatic control of the return temperature to solid fuel heating sources. Hot forged brass body with pipe union connections. Yellow brass finish.
• Maximum working pressure: 10 bar.
• Maximum temperature: 100°C.
• Calibration temperatures: 45°C, 55°C, 60°C and 72°C.
• Seal: watertight between the A-AB ports; 3% leak rate of Kvs between B-AB ports.
• Easy service or replacement of the sensor to change the calibration without removing the valve from the installation.
