Valve closing device for loading and unloading tanks with compressor-depressor, characterized in that it is constituted by a body provided with an upper cover and a lower base whose body internally determines two longitudinal cavities that are communicated with a common entrance through the cover, and which in turn extend through the base in independent conduits open to the outside, provided in each of these respective cavities respective valvular closing pistons, said pistons arranged in opposite directions of closure the one and the another cavity, further going, in the extension duct of the chamber provided with the closing direction piston to the drive from the inlet of the lid, a floating ball valve closure opposed to said piston closure; all this in such a way that a valve assembly is obtained that efficiently allows the filling and unloading of the tank to which it is applied, serving as a perfect closure, in order to avoid in any case that the product can reach the corresponding compressor-depressor.
