<p>A valve arrangement (1) for controlling a flow of a heating or cooling fluid is provided, said valve arrangement (1) comprising: a housing (2) having an inlet (3) and an outlet (4), a pressure regulating valve (11) being arranged between said inlet (3) and said outlet (4) and having a regulating valve element (12) and a regulating valve seat (13), said regulating valve element (12) being connected to a membrane (15), said membrane (15) having a flexible part (17) and being loaded on one side by an inlet pressure at the inlet (3) and on the opposite side by an outlet pressure at the outlet (4). In such a valve arrangement the risk of damages should be reduced. To this end a membrane supporting structure (25, 27, 28) is provided, said supporting structure (25, 27, 28) supporting said flexible part (17) of said membrane (15) when a force or a pressure acting on the membrane (15) exceeds a predetermined value.</p> |
