ASV valves are an efficient automatic balancing solution for various riser based heating applications, particularly radiator heating in residential buildings. A riser is controlled by two valves.
In the return an ASV differential pressure controller is mounted. There are two types of differential pressure controller: The ASV-P is a differential pressure controller with a fixed setting of 10 kPa. The ASV-PV is an adjustable differential pressure controller available for several Dp setting ranges, also depending on dimensions of the valves: 5 to 25 kPa, 20 to 40 kPa, 35 to 75 kPa, and 60 to 100 kPa. In the supply an ASV-I or ASV-M is mounted. The ASV-M is a manual shut-off valve and the ASV-I is a manual presetting/balancing valve that can be used to limit the flow.
