A hydraulic control valve for controlling a dual-action working cylinder exhibiting a piston with a unilateral piston rod, wherein the control valve designed like a piston valve exhibits at least four external connections with allocated ring channels (23, 24, 25, 26, 27, 29, 29a) formed in the valve housing, specifically a pump connection P, a connection A1 for a supply and discharge line to the large displacement of the working cylinder, a connection B for a supply and discharge line to the small displacement of the working cylinder, and a tank connection T1 joined with the tank, and wherein a control piston of the control valve exhibits piston bundles with control edges arranged thereon, which can be used to join the connections P, A1, B, T1 in the two positions of the control piston in such a way that, during the working stroke of the working cylinder, the fluid expelled from the small displacement while extending the piston rod is led back into the large displacement of the working cylinder, and a connection of the small displacement with the tank can be switched in order to switch the working cylinder from the working stroke to a slow speed followed by a stopped state so as to relieve the pressure of the small displacement of the working cylinder, wherein the control valve exhibiting at least three piston bundles with five control edges formed thereon is provided with two separate line paths with line strands (41, 42) for the fluid expelled from the small displacement during the working stroke of the piston, which branch into a branching of the supply and discharge line hooked up to the small displacement of the working cylinder and form the two line paths, of which a first line strand designed for recovery joins the supply and discharge line hooked up to the small displacement with the large displacement of the working cylinder by means of a recovery control edge formed on the piston bundle, and a check valve with a passage direction oriented toward the large displacement is incorporated into the first line strand, and the second line strand designed for joining the small displacement with the tank runs over a pressure relief control edge formed on an allocated piston bundle of the control valve, characterized in that the control edges formed on the piston bundles are each designed as recesses (32, 33, 34) arranged on the exterior sides of the piston bundle, and that the first line strand has allocated to it the piston bundle with the recess comprising the feedback control edge, and the second line strand has allocated to it the piston bundle exhibiting the pressure relief control edge comprised of the recess, wherein, in the position of the control piston valid for the working stroke of the cylinder, the feedback control edge formed by the recess establishes the connection between the first line strand and large displacement of the working cylinder, and the pressure relief control edge formed by the recess establishes the connection between the second line strand and the tank via an externally activatable stop valve housed therein for switching the discharge line (37, 45) that incorporates the working cylinder, wherein the recess forming the pressure relief control edge in the allocated piston bundle is rated for the fluid stream expelled from the small displacement of the working cylinder at a slow speed, and given smaller dimensions than the recesses (32, 33) of the piston bundle comprising the additional control edges.
