Vaillant 0020110996 gas valve

A genuine Vaillant part, this gas valve is compatible with ecoTEC VUW (condensing), ecoMAX VU (condensing), ecoTEC VU (condensing) and ecoMAX VUW (condensing) 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).
