Abstract

A parking brake valve assembly for a pneumatic braking system of a vehicle includes a first parking brake valve unit and a second parking brake valve unit. The first parking brake valve unit is actuated by a first parking brake signal and is switchable from a first to a second switching position, and the second parking brake valve unit is actuated by a second parking brake signal and is switchable from a first to a second switching position. The first and second parking brake signal are mutually independent. The first and second parking brake valve unit are pneumatically connected in series between a parking brake supply connection and a parking brake working connection such that the parking brake working connection can be both ventilated and vented independently of the switching position of one of the parking brake valve assemblies by switching the other parking brake valve assembly.
