AB-QM PICV
Best-in-class PICV (Pressure-independent balancing and control valves) with scaling and clogging-resistant design
Danfoss AB-QM was the first of its kind control valve for HVAC heating and cooling applications. AB-QM 4.0 is its next-level successor.
The basic principles haven’t changed; It is a control valve with automatic flow limitation and a built-in differential pressure controller. The control performance is very accurate, and the valve has a still unique valve authority of 100%.
