Danfoss AVQM is a combined flow controller and control valve designed for hydraulic balancing of heating and cooling systems. The device maintains the set flow rate at a constant value regardless of changes in differential pressure in the network, thereby eliminating the need for repeated system balancing. By integrating two functions into one compact body, it reduces the number of fittings required and simplifies both installation and operation.

The valve is made of high-quality brass and features an external connection for a differential pressure sensor or flow measurement. The spindle with precise adjustment allows smooth flow control by means of a rotary dial with a numerical scale. Typical applications include apartment buildings, commercial buildings and industrial facilities at riser branches, manifolds, or in fan coil and heat exchanger connections.
