摘要： The ball valve device comprises a tubular body (10) in metal material, having a cylindrical wall (11) conformed with spherical cup-shaped internal protrusions (13A) to retain a ball shaped valving member (14), preventing the same valving member (14) from being entrained by a fluid flowing through the valve device. The internal spherical protrusions (13A) are formed by radially pressing and crimping the cylindrical wall (11) of the tubular body (10) at one or more angularly spaced apart deformable areas of an annular strip (12). The tubular body (10) provided with the ball retaining protrusions (13A) is suitable for any valve device, such as ball check valves (25), pumping units (35), and/or ducts.
