Device for mounting the guide shaft in ball valves, which is characterized by the fact of being formed by two elastic washers, of convex configuration, attached to each other in such a way that they form a lenticular assembly, biconvex externally, which rests with the effect of spring on both sides on respective stops threaded to the guide shaft, of which the lower one rests on the valve body, while the upper one does it against the lower part of the operating handle mounted on the upper end of the guide shaft, therefore, both spring washers tend to maintain the latter with a certain tension against its inner seat of the valve body and allowing to automatically neutralize any slack or tolerance of the shaft, carrying out the assembly of the latter by the interior of the mentioned body and remaining the set locked by the application of the handle, consecutive to the insertion of the spring washers and their respective supports on the axis.
