Abstract

A ball valve (1) comprises a body (2) which delimits an inlet section (3), an outlet section (4) and a central portion (5), a first path which develops between the inlet section (3) and the outlet section (4) for the passage of a fluid, a selectively rotatable ball shutter (6) to allow or prevent the passage of a fluid along the first path, a second path which develops between the outlet section inlet (3), the shutter (6) and the outlet section (4), wherein the ball valve (1) comprises a check valve (11) positioned along the second path, wherein a pre-established pressure difference between the inlet section (3) and the outlet section (4) determines the opening of the check valve (11).
