Claim:
1. A control valve device for a highly available pneumatic brake system for a rail vehicle, the device comprising, a compressed air input, which is selectively connected to an output of a triggering valve device, and by which a defined input pressure can be fed to the control valve device; a compressed air output, which is connected to an input of a relay valve device and by which an output pressure can be fed to the relay valve device; and a safety input, which is selectively connected to a compressed air supply; wherein, in a first switch position, the control valve device fluidically connects the safety input to the compressed air output and in a second switch position it fluidically connects the compressed air input to the compressed air output; wherein, in the second switch position, the control valve device is designed to modify the input pressure according to a control device to provide the output pressure, and wherein the safety input is selectively fluidically connected to an output of the triggering valve device by a bypass line.
