The invention relates to a parking brake valve (12) for a trailer (202) that comprises a supply port (10) for connecting to a pneumatic pressure supply line (206) of a tractor (300), a delivery port (18) for connecting to a parking brake actuator (228), preferably via a braking module (226), an exhaust port (24) and an internal line (30, 31). Further- more, the parking brake valve (12) comprises a main valve (26), comprising a first posi- tion (48) connecting the internal line (30, 31) to the delivery port (18) for providing a pneumatic pressure at the internal line (30, 31) to the delivery port (18) and a second position (32) for connecting the exhaust port (24) to the delivery port (18) for discharging a pneumatic pressure at the delivery port (18) to the exhaust port (24). Moreover, the parking brake valve (12) comprises an internal valve (28, 29), comprising a first position (50) connecting the supply port (10) to the internal line (30, 31) for providing the pneu- matic pressure at the pneumatic pressure supply line (206) to the internal line (30, 31), a second position (36) blocking the connection between the internal line (30, 31) and the supply port (10) and a pilot port (16) for connecting to a pneumatic pressure control line (210) of the trailer (202) connected to a tractor (300), wherein the internal valve (28, 29) is arranged to switch from the second position (36) to the first position (50) when a pneumatic pressure above a switching pressure threshold value (78) is provided on the pilot port (16). The invention further relates to a braking system for a trailer, a vehicle (200), a vehicle combination (100) and a method (68) for controlling a parking brake (230).
