What it is

The GLOW 20103365 NO RETURN VALVE is a non-return valve supplied under the Glow-worm brand. It is a one-way valve that permits flow in a single direction and closes against reverse flow within the pipework or hydraulic circuit it is installed in. It is listed as a miscellaneous component rather than an appliance-specific spare.

Before you order

  • Confirm the part number 20103365 matches the item referenced in your appliance documentation or parts list.
  • Check the connection type, thread and size of the valve against the pipework it will be fitted to before ordering.
  • Verify that a non-return valve is the correct component for the position in the circuit you are working on.
  • Check flow direction requirements on site so the valve is installed the correct way round.
