What it is
The Vaillant 0020240266 is a gas control valve used on Vaillant Ecotec Pro and Ecotec Sustain VUW combi boilers. It regulates the flow of gas to the burner under the boiler's modulation control, so gas input matches demand for heating and hot water. The valve is supplied as a single component for replacement on the listed appliance variants.
Signs this part needs replacing
- Boiler fails to light or locks out repeatedly despite an ignition spark being present
- Gas input cannot be modulated, giving poor flame stability or rough running
- Flame picture changes or the burner extinguishes shortly after ignition
- Gas valve body shows signs of leakage, contamination or seized internal components
- Fault codes relating to gas valve position or flame supervision are logged
Before you order
- Confirm the boiler model and variant against the fit list above, including whether the appliance is natural gas or LPG
- Check the existing valve's part number matches 0020240266 before removal
- Work on the gas valve must be carried out by a competent Gas Safe registered engineer
- Verify the appliance's GC number against the boiler data badge to confirm the correct variant
