The Danfoss AB-QM pressure independent balancing and control valve (PICV) is an all-in-one balancing valve and differential pressure controller, providing 100 percent valve authority, accurate flow limitation and precise system control of hydronic systems. Available in a full range of sizes from ½-inch to 10-inches with a compact design able to handle any size application, the AB-QM is ideal for small spaces such as fan coil units and VAV boxes, as well as large buildings like offices, universities, hospitals, and buildings where accurate temperature control is critical, such as laboratories and research facilities.
With third-party verified balancing and control accuracies of ±5 percent of setpoint, the AB-QM is one of the most accurate valves on the market and can increase energy savings by 20 to 50 percent, improve overall system efficiency, and enhance indoor comfort. Compared to traditional balancing valves, the Danfoss AB-QM PICV eliminates the need for authority calculations and will save time on installation and commissioning.
The AB-QM pressure independent control valve helps to put an entire hydronic system into perfect balance by providing flows that match loads, even at partial loads, while minimizing maintenance and the horsepower required by the pump. This enables chillers to operate at designed capacities.
