Danfoss AB-QM is a DIAPHARGM type pressure independent balancing control valve that combines high accuracy and durability with market-leading user-friendliness and extensive sizes from DN10 to DN250. It also has a wide range of actuators such as thermal actuator and gear actuator to cope with the requirement of the user.

Pressure Independent valves are control valves with an automatic balancing function. An in-built pressure controller keeps a constant differential pressure over the control valve, ensuring full authority and automatic flow limitation.

By combining two functions in one, Control and Automatic Hydronic Balance, Danfoss PIBCV provides a cost-efficient solution for the challenges faced by forward-looking designers of HVAC system.

Danfoss AB-QM valve combined together with the new Novocon Digital Actuator is a 4-in-1 state-of-art PIBCV. This product comes with fewer items and greatly reduced the cost of commissioning, installation and maintenance time as compared to the traditional manual balancing valves and two-way valves.
