The motorized ball valve is the most common device and used of interception or deviation of the flow in plumbing pipes. Its operation is based on the 90 ° Rotation of a shutter Cylindrical Ball Complete with a hole or more holes. The valve allows the passage or the total closure of the flow but in some cases also its adjustment. A full flow ball valve, that is, in which the diameter of passage is equal to the internal diameter of the tube upstream and downstream, presents a loss of load rather low and equal to that of the tube, if the valve is fully open. The valves may be to 2 way or 3 way.
