What it is

The Vaillant 0020236142 is a two way valve used in Vaillant unvented hot water cylinder installations. It controls flow through the cylinder pipework as part of the appliance's hydraulic circuit. The valve is supplied by Vaillant for the Vantage VIH and VIH cylinder ranges.

Signs this part needs replacing

  • Water passing through the valve when the circuit should be closed
  • Flow not being diverted or isolated as expected during operation
  • Visible weeping or dripping from the valve body or spindle
  • Stiff or seized operation when the valve is actuated
  • Cylinder performance changes that trace back to restricted or uncontrolled flow through the valve

Before you order

  • Confirm the cylinder model and index from the data badge against the fit list above
  • Check the part number 0020236142 on the existing valve or the manufacturer's parts list
  • Inspect the surrounding pipework and connections for damage before fitting
  • Verify whether any other components in the same circuit also need attention
