Additional Information

AB-QM™ –
Simple, Affordable, Comfort.

Pressure independent control excellence from the global market leader for over 30 years.

Discover how Danfoss AB-QM™ Pressure independent control valves (PICVs) can improve system efficiency by eliminating overflows and increasing ΔT.

What is Danfoss AB-QM™ ?

AB-QM™ is a pressure independent control valve with a built-in, integrated differential pressure regulator. The unique design allows the valve to be selected via required flow versus traditional Cv calculations.

When equipped with a perfectly matched Danfoss electric actuator, AB-QM™ PICVs increase energy efficiency & room temperature control, improving indoor climate conditions. PICVs are typically found in HVAC heating and cooling systems.


Typical AB-QM™ PICV applications include:

  • air handling units
  • climate ceilings
  • variable air volume boxes
  • fan-coil units
  • terminal units
