Brahma Solenoid coil 18811000

This is a solenoid coil from Brahma. It is an electromagnetic actuator with a threaded core or push-on mounting. It has a terminal board electrical connection and IP54 protection. It operates on AC supply and has a built-in rectifier. It is designed to fit Brahma valve series.

Coils of this type are selected by their operating voltage and the specific valve body series they are designed to fit. Before installation, confirm the voltage rating matches the burner supply and ensure the mounting interface — either threaded core or push-on — corresponds to the valve body. Replace with the identical part number to ensure correct magnetic performance and mechanical fit.

Typical failure modes include open-circuit windings due to thermal stress and shorted turns from moisture ingress. A burnt-out coil prevents the valve from opening, causing a lockout on the burner control. In some cases the coil may still draw current but fail to generate sufficient magnetic force to lift the plunger, particularly if the valve seat is sticking.
