An adjustable flow-control valve is for controlling the flow from a fluid-supply unit. The control valve includes a pressure-control unit and a flow-control unit, a first inlet for connection to the fluid-supply unit, and an outlet. The pressure-control unit includes a first chamber (I) and a second chamber (II) separated by a first movable element which is cooperatively connected to a first preloading device, the first chamber being in fluid communication with the first inlet and with the flow-control unit, and the second chamber being in fluid communication with the outlet of the flow-control valve and including a second inlet in fluid communication with the flow-control unit. The flow-control unit includes a third chamber (III) and a fourth chamber (IV) separated by a second movable element which is cooperatively connected to a second preloading device.
