A parking brake valve assembly for an electronically controllable pneumatic braking system of a vehicle is disclosed. The parking brake valve assembly includes: a first compressed air path which receives a supply pressure and has a first monostable valve unit for providing a first parking brake pressure, a second compressed air path which receives supply pressure and has a second monostable valve unit for providing a second parking brake pressure, and a first shuttle valve having a first shuttle valve port with the first compressed air path and receiving the first parking brake pressure, a second shuttle valve port with the second compressed air path and receiving the second parking brake pressure, and a third shuttle valve port connectable to a spring brake cylinder. The first shuttle valve outputs the higher of the first parking brake pressure and of the second parking brake pressure to the third shuttle valve port.
