Three-way stopcock with spherical valve and programmer control, characterized as being of a body equipped with three ways, one of entrance, another of passing and another of service located on the one of step, so that any of these two ways could be sealed by a ball valve that runs inside the body of the key; said shutter movement is produced by a single-acting hydraulic cylinder, operated by a regulating valve which in turn is controlled by a programmable cam-wheel driven by means of a volumetric counter activated through an impeller installed in the service way of the key, so that by turning the impeller through the water passage, the counter, constituted by a suitable reduction system, rotates the programming cam on whose edge it contacts a shut-off piston housed in the distributor valve, so that when jumping said piston when it reaches the depression of the cam, a water passage is opened, coming from the body of the valve itself, and through a suitable conduit it enters the hydraulic cylinder for actuating the ball valve.
