Abstract: A valve arrangement comprising a valve housing, a valve inlet, a valve outlet and a diaphragm assembly for controlling a fluid flow through the valve housing from the valve inlet to the valve outlet, the diaphragm assembly comprising a diaphragm and a diaphragm plate at least partially covering the diaphragm, the diaphragm comprising one or more equalization holes passing through the diaphragm and the diaphragm plate comprising one or more equalization openings passing through the diaphragm plate, the equalization holes being aligned with the equalization openings. The diaphragm assembly comprises an engagement zone engaging the diaphragm in order to rotationally fix the diaphragm and the diaphragm plate with respect to each other so that the equalization holes will keep aligned with the equalization openings to ensure proper function of the valve arrangement at all times.
