The invention relates to a bistable relay valve for an electropneumatic brake control device (1), comprising a relay piston (46) which can assume a first end position, a second end position and a plurality of intermediate positions between the first end position and the second end position, a control chamber (42) which is bounded by the relay piston (46) a pneumatic control input (20), which is always connected to the control chamber (42), for inputting control pressure from a control pressure generator (8) into the control chamber (20) for actuating the relay piston (46), an output port (28) for outputting a working pressure at least one supply port (16), for controlling a supply pressure, an exhaust port (56), a double-seat valve comprising an inlet valve (74) and an outlet valve (78) and actuated by the relay piston (46) and a working chamber (58) connected to the outlet port (28), a supply chamber (60) connected to the at least one supply port (16), wherein in the first end position of the relay piston (46) the working chamber (58) is brought into communication with the exhaust port (56), and in the second end position the working chamber (58) is brought into communication with the supply chamber (60), wherein, when the relay piston (46) has reached the first end position, a first flow connection is established in which the control chamber (42) is connected to the exhaust port (56), and when the relay piston (46) has reached the second end position, a second flow connection is established in which the at least one supply port (16) is connected to the control chamber (42). This stabilizes the end positions of the relay valve (18).
