Diafragma «D.3» para metano (azul) De Dietrich JJJ030006942

The Diaphragm D.3 Methane (Blue) is a flexible membrane used in gas valves for methane applications. Its blue color distinguishes it from other types, and it plays a crucial role in modulating gas flow based on pressure differentials. A worn or damaged diaphragm can cause erratic burner operation, poor combustion, or safety hazards. Replacing it with the correct D.3 methane diaphragm helps restore precise gas control and ensures your heating equipment runs efficiently and safely.
