The three piece handle ball valve belongs to the manual ball valve category. A ball valve is a valve that uses a ball with a circular channel as the opening and closing element, and the ball rotates with the valve stem to achieve the opening and closing action. The opening and closing component of a ball valve is a perforated sphere that rotates around an axis perpendicular to the channel to achieve the purpose of opening and closing the channel. Ball valves are mainly used to cut off or connect pipelines and equipment media, and can also be used for fluid regulation and control. Ball valves have low fluid resistance, simple structure, small volume, light weight, tight and reliable, easy operation and maintenance, will not cause erosion of valve sealing surfaces, and have a wide range of applications.
