Plunger De Dietrich 722305600

A plunger is a moving component within gas valves or actuators that opens or closes passages to control flow. This boiler spare part is subject to wear from friction and thermal cycling. A sticking or worn plunger can lead to inconsistent burner operation or failure to modulate. Replacing the plunger restores smooth mechanical action and reliable performance. Often used in valve repair kits, this part is a common replacement during maintenance of heating equipment. Ensure compatibility with your specific valve model for best results.
