The invention relates to a valve arrangement, especially such as a heat exchanger valve arrangement, having a pressure control valve, said pressure control valve comprising a valve element cooperating with a throttling element and controlling a differential pressure. Furthermore, the invention relates to a method for making functionally check on the valve arrangement, where a sensor measures the position of the valve element and where the measured position is compared to an expected position to give an indication if the valve arrangement are operating according to the expectations.
