Electropneumatic control valve for a pneumatic brake system of a vehicle having a relay valve housing in which an axially adjustable control piston is arranged for actuating a valve seat arrangement which switches the compressed-air flow between at least one exterior brake line connection, a supply pressure connection and a bleeder connection. The control piston is axially guided by means of a coaxial guiding arrangement. The guiding arrangement comprises a separate guiding sleeve which is stationarily fastened to the pilot valve housing and which is provided with an upper guiding section which, for the axial guidance, corresponds with a passage bore in the control piston, and which, in addition, has a lower tube section of a smaller outside diameter adjoining the upper guiding section in order to guide the outgoing air flowing through an integrated axial bleeder duct directly to the bleeder connection.
