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, PIBCV's 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.
