Valve device for a system, in particular a braking system for a vehicle, and system, in particular braking system for a vehicle

A valve device for a system for a vehicle, the system having a first control unit and a second control unit, wherein the control units are electrically connectable or connected to the valve device, comprising:

• a valve unit for setting a pressure of a working medium for the system, wherein the valve unit has at least one actuator for actuating the valve unit;
• a valve housing for accommodating the valve unit;
• and
• an error protection module, which is arranged outside the valve housing, wherein the error protection module has a first supply port for the electrical attachment to the first control unit, a second supply port for the electrical attachment to the second control unit, a first main port for the electrical attachment to the first control unit, a second main port for the electrical attachment to the second control unit, a first connection port, which is electrically connected to the first supply port and to the second supply port, for the electrical connection to the actuator, a second connection port, which is electrically connected to the first main port and to the second main port, for the electrical connection to the actuator, a first electric protective circuit and a second electric protective circuit, wherein the first protective circuit is electrically connected between the first supply port and the second supply port, and the first connection port, wherein the second protective circuit is electrically connected between the second connection port, and the first main port and the second main port, wherein at least one of the protective circuits has at least one electrical fuse device and/or at least one diode element that are connected in series to the respective supply port or main port;
• wherein the valve unit has at least one further actuator for actuating the valve unit, wherein the second connection port of the error protection module is electrically connectable or connected to the further actuator, wherein the error protection module has at least one third supply port for the electrical attachment to the first control unit, at least one fourth supply port for the electrical attachment to the second control unit, at least one further connection port, which is electrically connected to the third supply port and the fourth supply port, for the electrical connection to the further actuator, and at least one further protective circuit, wherein the further protective circuit is electrically connected between the third supply port and the fourth supply port, and the further connection port.
