Abstract
A changing device for coating media having a plurality of supply units. The device includes an electric valve device with each supply unit having an electric valve unit which opens and closes a flow channel through which a medium may be supplied in response to a control signal. The valve device includes a control system which has a switching device for each supply unit, each switching device selectively allowing or blocking a control signal from reaching a respective valve unit. The valve device also includes a triggering device which is carried by at least one coupling unit which couples the plurality of supply units to an application device. The triggering device triggers the switching device to allow the control signal through to a supply unit when the coupling unit is connected to the supply unit in a fluid-tight manner.
