The magnetic coil is a genuine spare part for ACK wok cookers and fits inside the S22 Safety Gas Valve.
Magnetic coils within the flame safety device (FFD) are energised by the power generated when the thermocouple is heated by the bar burner. In the event the flame is extinguished, the FFD Magnetic Coil within the gas safety valve will close, and the gas flow is automatically switched off.

Needed this with the safety valve. Seems like its going to work ok.
