ABSTRACT OF THE DISCLOSURE A hydraulic valve for programmed and remote switching over of pipelines, where the body of the valve has three vertical pipes which axes lie in a single plane. A first vertical pipe is connected at its lower end to a horizontal inlet pipe, while connected at the upper end, through an elbow to the side of a second vertical pipe. The latter is connected at its upper end, through a second elbow, to a horizontal out- let, while its lower end, under the opening toward the first vertical pipe, via a third elbow is connected to the side of the third vertical pipe. The third vertical pipe is connected at the upper end to the vertical outlet pipeline, while at the lower end, via a fourth elbow, is connected to the side of the first vertical pipe, where a free float is placed. With the horizontal inlet pipeline a gravitational valve with a dis- charger is foreseen, while on the horizontal outlet pipeline there is a check valve. Along the outer diameter of the upper part of the float a planar ringlike packing edge is machined, while its bottom part has a semispherical shape and is filled with heavier than water ballast material. The diameter of the float is smaller than the diameters of the three vertical pi- pes, while its length is shorter than the lengths of the ver- tical sections of these pipes, respectively above and bellow the openings connecting the pipes with each other. The floats diameter is greater than the diameters of the horizontal in- let and outlet pipelines and that of the vertical outlet pi- peline. The upper end of the discharge is lower than the level of the bottom end of the first vertical pipe.
