Maxitrol M411B9 Plunger What are the symptoms ofThe Maxitrol M411B9 is a high precision modulator head plunger engineered specifically for the MR212 series of gas pressure regulators and modulating valves. Within the Selectra electronic gas flame modulation system, this plunger acts as the critical mechanical interface between the electrical solenoid signal and the gas flow regulation. When the amplifier applies DC voltage (typically ranging from 10 to 13 Volts DC on MR212 models), the resulting
