80+ Years of Sustainability

Danfoss has been engineering innovations designed to enhance comfort & save energy for over 80 years. Learn more about our sustainable building technology like AB-QM™ in our Sustainable Buildings video below...

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

AB-QM™ Features & Benefits

Mechanical pressure independent technology

Integrated differential pressure regulator for exceptional flow control.

Easy setting and sizing

Selecting the right AB-QM™ is much less complicated than sizing and selecting conventional control valves, and no Cv calculations are required.

Wide range of valve sizes

Valves are available in ½” through 10”, covering a wide variety of HVAC applications.

Field adjustable flow setting

No tools are required for the ½" to 1-¼" valves. Simply lift, rotate, and lock valve adjustment knob on your required flow setting. 

Tight close-off/clog resistant

Unique two-stage close off resists debris.
