What it is

The Vaillant 0020010295 is a valve supplied as a spare component for Vaillant heating appliances. It belongs to the valves and connections group of boiler spares, the parts that isolate, regulate or direct water around the appliance's hydraulic circuit. The valve is supplied as a single unit and is intended as a like-for-like replacement for the component carrying the same part number.

Valves of this type are working parts: they are opened, closed or modulated repeatedly over the life of the appliance, and their seals and seats wear as a result. Replacing the valve restores correct control of flow through that section of the circuit.

Signs this part needs replacing

  • Water weeping or dripping from the valve body, spindle or connections
  • System pressure that drops and will not hold after topping up
  • Restricted or uneven flow through the affected part of the circuit
  • A spindle or handle that no longer turns freely, or will not close fully
  • Scale, corrosion or debris visible around the valve seat or outlet

Before you order

  • Check the part number on the existing valve or in the appliance's installation and servicing manual.
  • Note the appliance model and serial number so the correct variant is matched.
  • Inspect the mating faces and washers on removal; a seal or gasket may be needed to complete the repair.
  • Isolate and drain the appliance before removing the old valve.
