What it is

The Danfoss 003Z8204 is an AB-QM valve supplied in the DN20 high flow variant with an external thread connection. It is a pressure-independent balancing and control valve used on hydronic circuits, where it combines flow limiting with control of the circuit it serves. The valve is manufactured by Danfoss and identified by part number 003Z8204.

Before you order

  • Confirm DN20 is the correct nominal size for the circuit and that the external thread connection matches the mating pipework or fittings.
  • Check that the high flow variant is the version required for the design flow rate of the circuit.
  • Verify part number 003Z8204 against the system documentation or against the valve being replaced.
  • Consider whether any actuator or commissioning accessory is required to complete the installation, as these are ordered separately unless stated.
