Without pressure independent technology, it can be incredibly challenging to maintain the balance of an HVAC system, but with AB-QM’s revolutionary technology the compact automatic balancing valve and the pressure independent control valve have combined into one comprehensive valve structure.  AB-QM offers superior temperature control and performance compared to other pressure independent control valves on the market.

One of the most obvious advantages of this valve when compared with conventional two-way valves and manual balancing valves is that fewer products and or parts are required. This cuts down on installation and commissioning time, takes away the need to do any kind of manual balancing of the installation and reduces calculations significantly. All that is needed is the required flow and the AB-QM will automatically balance the installation immediately after having been installed

There have been close to 2 million AB-QM valves installed internationally over the past 10 years.  See Project References and Case Studies
