Data sheet Description / Application (continuous) Automatic balancing valves ASV Fig.3 ASVinriser/typicalheatingapplication(generalexample) ASV valves are to be used in radiator heating systems to control the differential pressure in risers. To limit the f low for every radiator, the thermostatic radiator valve with pre-setting facilities (feature) is used together with a constant pressure provided by the ASV, thus providing balanced heat distribution. Alternatively the f low in the riser can be limited by using setting function of the ASV-I. Controlling differential pressure over the riser means also that the valve authority over the thermostatic radiator valves is high – which allows an accurate and stable temperature control and saves energy. Fig.4 ASVinmanifoldforfloorheatingsystem ASV valves are to be used in f loor heating systems. To limit the f low for every loop valves with an integrated f low limiting or presetting function should be used together with a constant pressure provided by an ASV-PV valve. Alternatively the f low for the whole manifold can be limited by using the setting function of the ASV-I or ASV-BD. ASV-PV valves can control the differential pressure in several ranges if different pressure is needed. Due to its small dimensions the ASV automatic balancing valves are easy to install in a wall mounted box for f loor heating manifolds. DEN-SMT/SI VD.A6.E1.02 © Danfoss 06/2012 3
