What it is

The Vaillant 8000010453 is a gas isolation valve with a 15/22 connection designation. It is fitted on Vaillant Ecotec appliances to allow the gas supply to be isolated for servicing and repair work. The valve is operated to shut off gas flow to the appliance without disturbing the rest of the installation.

Signs this part needs replacing

  • The valve spindle is stiff, seized or will not turn through its full travel
  • Gas is weeping from the spindle gland or the valve body
  • The valve will not shut off the gas supply fully when closed
  • The operating handle or square is rounded, cracked or missing
  • Visible corrosion or mechanical damage to the valve body or connections

Before you order

  • Check the appliance data badge to confirm the model and GC number match the fit list
  • Confirm the existing valve carries the same 15/22 connection designation
  • Check there is sufficient access to the valve position for removal and refitting
  • Confirm the gas supply is isolated and the appliance is safe to work on before starting
