VALVE DEVICE FOR A SYSTEM FOR A VEHICLE AND SYSTEM FOR A VEHICLE

A valve device or a vehicle system, the system including first and second control units which are electrically connectable or connected to the valve device, which includes a valve unit with at least one actuator for actuating the valve unit, first/second supply ports for the electrical connection of the actuator to the first/second control units, first/second main ports for the electrical connection of the actuator to the first/second control units, first/second electric protective circuits, and a valve housing for accommodating the valve unit and the protective circuits. The first protective circuit is electrically connected between the first/second supply ports, and the actuator. The second protective circuit is electrically connected between the actuator and the first/second main ports. Each protective circuit includes an electrical fuse device and a diode element that are integrated in series in at least the first/second supply ports or at least the first/second main ports.
