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 (VD) for a vehicle-braking-system (VBS), and a VBS. A VD for a VBS, having first/second control-units (CU), which are electrically connectable to the VD, which includes a valve-unit (VU) with an actuator for actuating the VU, a valve housing (VH) for the VU, and an error protection module (EPM) outside the VH. The EPM includes first/second supply-ports (SP) for electrical attachment to the first/second CUs, first/second main-ports (MP) for electrical attachment to the first/second CUs, a first connection port (CP) electrically connected to the first/second SPs, for electrical connection to the actuator, a second CP electrically connected to the first/second MPs, for electrical connection to the actuator, first and second electric protective circuits (EPC). The first EPC is electrically connected between the first/second SPs, and the first CP. The second EPC is electrically connected between the second CP and the first/second MPs. An EPC includes an electrical fuse-device and/or a diode-element connected in series to the respective supply/main ports.
