What it is

The Vaillant 0020143482 is a gas control valve used on Vaillant ecoTEC VU 806/5-5 R-series gas boilers. It regulates the supply of gas to the burner in line with the boiler's modulation control. The valve is supplied as a single component for replacement on the appliance variants listed below.

Signs this part needs replacing

  • The boiler fails to light or locks out repeatedly with an ignition or flame-detection fault.
  • The burner flame is weak, unstable or inconsistent across the modulation range.
  • The valve body emits a humming or buzzing noise during operation.
  • Corrosion, debris or moisture is visible around the valve body or its connections.
  • Gas pressure readings at the valve fall outside the manufacturer's stated range.

Before you order

  • Confirm the boiler model against the fitment list above.
  • Check that the part number on the existing valve matches 0020143482.
  • Gas-carrying components must be fitted by a Gas Safe registered engineer.
  • Check whether any seals, gaskets or pipework connections also need replacing.
