Abstract

A valve arrangement is provided, () comprising: a valve () for controlling a flow of heating or cooling fluid through a heat exchanger, an actuator () for actuating said valve (), control means () for controlling said actuator (), a first temperature sensor () connected to said control means (), a thermal resistance between the first temperature sensor () and the valve () being greater than a thermal resistance between the second temperature sensor () and the valve (). It is intended to improve control of the valve. To this end the first temperature sensor () and the second temperature sensor () are part of detector means detecting a closing condition of the valve ().
