What it is

The Danfoss AVDO 15 is an automatic by-pass valve with 1/2" BSP connections, supplied under part number 003L601800. It sits in a heating circuit and maintains a minimum flow through the heat source as system flow falls, opening automatically when the differential across the circuit rises. It is a system component rather than an appliance spare.

Before you order

  • Confirm 1/2" BSP matches the pipework connections at the intended installation point.
  • Confirm the AVDO 15 model and part number 003L601800 are the reference required for the system.
  • Check that the system design calls for an automatic by-pass valve rather than a fixed or manually set by-pass arrangement.
