AB-QM - Pressure independent control valves

  • 1 million reasons to choose the best

    The story of AB-QM started more than 10 years ago in Denmark. Talented engineers have developed a conventional two-way valve and manual balancing valve with an entirely new approach of calculating, commissioning and installing. 

    AB-QM is a control valve with full authority and an integrated automatic balancing function (flow limitation). AB-QM can be applied to all terminal units, from fan coil units to air handling units.

    Reliability transformed into an instant appreciation.


  • What's in it for you?


  • Easy setting and sizing

    Selecting the right AB-QM is much less complicated than sizing and selecting conventional control valves.

    100% authority

    Having a 100% valve authority increases the control quality and precision – also at low flow requirements. This creates
    a better comfort in the building, as well as energy savings.

    Perfect control

    By providing the right flow at the right time, the AB-QM optimizes chiller and boiler efficiency and reduces pumping costs.
