Improved ball valve, essentially characterized in that the axial turning rod acting as a transmitter of the driving force applied to its head to the ball-shaped sealing member, has at its lower end, close to the area of its coupling to the shutter, a threaded annular projection, conjugate of an annular projection derived from the internal orifice of the valve body in which the aforementioned stem is housed, allowing both threaded and conjugate zones the initial displacement by threading the stem towards the interior of the valve and making it impossible its accidental recoil by axial movement.
