Abrégé

A fluid-operated control device for double-acting actuators includes a valve body which integrates a first overcenter valve in which the inlet is connected to a distribution device by means of a first connecting branch and the outlet is connectable to a first chamber of at least one fluid-operated cylinder, the valve body further integrating a second overcenter valve in which the inlet is connected to the distribution device by means of a second connecting branch and the outlet is connectable to a second chamber of the fluid-operated cylinder, the first overcenter valve being actuatable by means of a first control branch which is connected to the second connecting branch and being provided with particular fluid throttling, check and drainage elements connected to the first connecting branch, the second overcenter valve being actuatable by means of a second control branch connected to the first connecting branch, the distribution device being provided with a control chamber and being automatically switchable between a first operating condition, in which the first connecting branch is connected to a delivery branch of a working fluid and the second connecting branch is connected to a return branch of the working fluid and the control chamber of the distribution device is connected to the return branch of the working fluid by means of a unidirectional throttle valve, and a second operating condition, in which the first connecting branch is connected to the return branch by means of the unidirectional throttle valve and the second connecting branch is connected to the delivery branch, the switching between the first operating condition and the second operating condition being controlled by an overpressure valve integrated in the valve body and having the inlet connected to the first connecting branch by means of a third control branch and the outlet connected to the control chamber of the distribution device.
