Glow-worm 2000801020 gas valve

This Glow-worm gas valve is suitable for Economy Plus, Protherm, Ultimate, Ikon and Xeon boilers. The gas valve is employed in the distribution of gas. When gas is required in the burner the printed circuit board (PCB) sends a signal to the gas valve, which opens to allow gas to flow into the burner or the pilot assembly (depending on the model of the appliance).
