What it is

The Vaillant 0020031979 is a thermostatic expansion valve rated at 17 kW. A thermostatic expansion valve is a metering device that regulates flow through a circuit in response to the temperature it senses. This unit is supplied as a single component for use where the 17 kW rating is specified.

Before you order

  • Confirm that 0020031979 matches the part number listed for your installation in the manufacturer's documentation.
  • Check that a 17 kW rated valve is the correct capacity for the circuit it is being fitted to.
  • Compare the connection arrangement and orientation of the new valve against the component being removed before starting work.
