The description relates to a device for the regulation of the amount of a medium in a heating or cooling system, comprising a combined valve, which in one and the same valve housing includes one part for pressure difference regulation () and one part for flow limitation (), the flow being limited in a stepless, adjustable way, i.e. the device obtaining an adjustable Kvs-value. Also, the chosen Kvs-value can be limited by a plunger, which always can operate with its complete stroke length.
