The invention discloses a coordinated valve for an uplock for a retractable actuating cylinder, and aims at providing a coordinated valve for an uplock, which is reliable in work, and large in coordinating action range, and is capable of preventing a latch hook and a guard plate lock ring from generating abnormal phenomena such as friction. The coordinated valve is achieved through the technical scheme as follows: when hydraulic oil enters the acting cylinder from an unlock pipe nozzle B of which the radical direction is perpendicular to the shaft end of an acting cylinder body, a steel ball (1) is attached to and sealed with an oil inlet of an axial coordinating action pipe nozzle A on the end surface of the actuating cylinder under the action of hydraulic pressure; when the coordinating action pipe nozzle A is led to the actuating cylinder of a guard plate, the hydraulic oil can only push an uplock piston (6) to move towards the right; when the movement distance reaches the coordinating action travel, a nut (8) contacts a baffle ring (7), and drives a rod body of a valve body (2) to move towards the right; the valve body (2) is driven to drive the steel ball (1) to move and to be broken away from the oil inlet of the coordinating action pipe nozzle A; and the coordinating action pipe nozzle A is intercommunicated with the unlock pipe nozzle B, and thus the function of the coordinating action valve is finished, and the coordinating order of firstly unlocking and then putting the guard plate is achieved by the uplock system.
