<p>A valve arrangement is provided, (1) comprising: a valve (2) for controlling a flow of heating or cooling fluid through a heat exchanger, an actuator (12) for actuating said valve (2), control means (15) for controlling said actuator (12), a first temperature sensor (18) connected to said control means (15), a thermal resistance between the first temperature sensor (18) and the valve (2) being greater than a thermal resistance between the second temperature sensor (19) and the valve (2).</p><p>It is intended to improve control of the valve.</p><p>To this end the first temperature sensor (18) and the second temperature sensor (19) are part of detector means detecting a closing condition of the valve (2).
