A pneumatic sequential control valve for successive aeration and deaeration of two consumers, wherein for purposes of aeration compressed air is initially applied to the first consumer and only subsequently to the second consumer, and for deaeration the compressed air is initially let off from the second consumer and only subsequently from the first consumer, comprises a valve body with connections for a compressed air line and a first consumer and second consumer, wherein a cavity is provided in the valve body, bore holes extend from the connections for the consumers and for the compressed air line to this cavity. A control slide is mounted in this cavity so as to be displaceable, wherein a control space is provided between an end side of the control slide, at which a piston surface is arranged, and the valve body, and this control space communicates, via a choke line, with the bore hole which is connected with the connection for the compressed air line, and the control slide is pretensioned in direction of its first end position by means of a spring arrangement.
