Diaphragm De Dietrich 722305500

A diaphragm is a flexible membrane that regulates gas or air flow in valves and pressure switches. This critical burner spare part responds to pressure changes to control burner operation. A worn or torn diaphragm can cause improper gas mixture, unstable flame, or system shutdown. Replacing the diaphragm is a cost-effective repair that restores precise control. Compatible with many gas valves and regulators, this component is essential for maintaining the efficiency and safety of your heating equipment during routine boiler maintenance.
