Danfoss AB-QM was the first of its kind control valve for HVAC heating and cooling applications. It is a control valve with automatic flow limitation and built-in differential pressure control functioning over the control valve. The result of this concept is a high performing control valve with a – still - unique valve authority of 100%. The design flow can easily be set to the needed amount by using a 20-100% scale. Simply setting the design flow replaces traditional commissioning processes, gives a much more accurate control and avoids Kv calculations for system designers.

When equipped with a Danfoss actuator, PICVs increase the energy efficiency and improve the indoor climate. The AB-QM is mainly used for air handling units, climate ceilings, fan-coil units and other terminal units in HVAC heating and cooling systems.

Features and benefits

Easy setting and sizing

Selecting the right AB-QM is much less complicated than sizing and selecting conventional control valves. Once the design flow is determined the matching AB-QM can be selected, no additional Kv and authority calculations are required.

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 increasing the 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. In addition, the actuators need to make much less movements, increasing the lifetime value and lowering the Total Cost of Ownership.

AB-QM 4.0: We created PICVs - now we redefine the value

New: AB-QM 4.0

Get ready for the next level value of your PICV designs.
