Danfoss ASV automatic balancing valves provide a simple, reliable and cost-effective way to create hydronic balance in two-pipe heating or cooling systems. They solve the technical issue of pressure fluctuations: the root cause of system imbalances and problems such as uneven heat distribution, noise and high energy consumption. ASV consists from two components; a return-pipe mounted differential pressure controller ASV-P or ASV-PV and flow-pipe mounted partner valve ASV-BD, ASV-I or ASV-M. An impulse tube connects both valves so the differential pressure over the riser can be controlled. In combination with Danfoss RA-N or RA-UN pre-setting valves on the radiators a perfectly balanced system, in both full and partial load conditions, is achieved.
The 4th generation of ASV-PV offers many unique product innovations. It is designed based on the needs from installers, designers and consultants with a focus on time saving during installation and commissioning of the system.
Features and benefits
Visible setting scale
Simple adjustment of the differential pressure setting, no special equipment is required. The clearly visible setting scale makes it easy to determine if the setting is adjusted correctly. The setting ring can be locked to prevent unauthorized adjustments.
Short build in height
The installation dimensions are decreased for flexible and convenient installation.
Faster and better flushing
Increase the reliability of the system by flushing it and remove before putting the system into operation. To flush and fill a system faster, the ASV-PV valve can temporarily be locked in an open position by a flushing ring accessory.
Integrated membrane
The valve body and pressure membrane are combined into one component. This design ensures optimal low flow performance and extremely ideal differential pressure sensitivity for each individual DN size valve.

Too warm, too cold, and no chance to regulate the heating inside the individual apartments—those were the issues facing the residents in a 9-storey apartment building in Tallinn, Estonia. By upgrading the existing one-pipe system into a two-pipe system with automatic hydronic balancing, the residents now enjoy improved comfort and 25 percent savings on the energy bill.

Some years ago, the radiators in five 9-storey apartment buildings in Milan, Italy were equipped with thermostatic radiator valves. Not until the system was fitted with automatic balancing valves, however, did the benefits of the new TRVs materialize in terms of 14 percent energy savings, less noise from the heating system, and improved indoor comfort for the residents.

During the past few years a huge demand for sustainable living has emerged. The pressure on creating environmental friendly or green buildings is higher than ever. Also for existing buildings the need for not leaving a big blueprint on the globe is becoming increasingly important. In Jönköping, Sweden, the community living in the Västerkåkar neighborhood is going forward. In 2013 substantial changes to the communal heating system in the buildings in four streets showed that a green example can be set, in just a couple of steps.
