What it is

The Danfoss 003Z8320 is an Ab-Qm pressure-independent balancing and control valve (PIBCV) with an internal threaded connection in DN15, supplied in the low flow variant. The Ab-Qm range combines dynamic balancing with control valve function, maintaining a constant set flow across the valve regardless of pressure fluctuations in the system. It is used on terminal units in hydronic heating and cooling circuits where flow limitation and accurate control are required.

Before you order

  • Confirm the valve is required in the low flow variant for the design flow rate of the terminal unit.
  • Check that an internal threaded DN15 connection matches the pipework and fittings on site.
  • Verify the actuator and any associated accessories are compatible with the Ab-Qm body being installed.
  • Check the system pressure and temperature conditions against the published Ab-Qm operating limits before installation.
