A fail-safety valve unit is for a failure braking function of a pneumatic braking system for a vehicle. The fail-safety valve unit has a first and a second failure brake valve configured as monostable valves, and a main line which pneumatically connects a main port, which provides a first pressure, and a failure port. The first and second failure brake valves are connected pneumatically in series in the main line. The first and the second failure brake valves are controllable by different control units. The failure brake valves are open in an open position when not actuated such that the first pressure prevailing at the main port is provided as a failure brake pressure at the failure port such that, in a fault situation, in an electrical failure, and/or in a diagnostic situation, a failure braking operation is triggered via provision of the failure brake pressure at the failure port.
