Description
This solenoid coil is a replaceable component for gas valves used in burners and boilers. It operates on DC voltage and connects via a two-wire cable, with IP65 protection. The coil mounts on top of the valve body and uses a spring return to close the valve when de-energised, so its default state is closed.
Choosing and fitting
Parts of this type are selected by brand and series to match the valve body. Before ordering, verify the coil voltage (typically 230 V or 24 V AC/DC) and whether the valve uses a single or double solenoid configuration. Ensure that the mounting matches the valve body top and that the electrical connection is compatible with the burner control output.
Signs of failure
Common failure modes include burnout from sustained overvoltage or overheating, and intermittent operation due to partial short circuits. When a coil fails, the valve may not open or close properly, causing the burner to lock out or operate erratically. Check the coil for signs of overheating or shorted turns, and inspect the valve seat and plunger for debris or wear, as these can lead to repeated coil burnout.
