A Brief Overview Of Ball Valves

The ball valve evolved from the cock. Its opening and closing part is a sphere, and the sphere is rotated 90o around the axis of the valve stem to achieve the purpose of opening and closing. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium on the pipeline. The ball valve designed with a V-shaped opening also has a good flow adjustment function.

The ball valve is not only simple in structure and good in sealing performance but also small in volume, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate, and easy to open and close quickly within a certain nominal diameter range. One of the fastest growing valve varieties in more than ten years. Especially in developed industrial countries such as the United States, Japan, Germany, France, Italy, the West, and the United Kingdom, the use of ball valves is very extensive, and the variety and quantity of ball valves are still expanding. , excellent adjustment performance and multi-function development of one valve, its reliability, and other performance indicators have reached a high level, and have partially replaced gate valves, globe valves, and throttle valves. With the advancement of ball valve technology, it will be widely used in oil and gas pipelines, oil refining crackers, and the nuclear industry in the foreseeable short term. In addition, ball valves will also become one of the dominant valve types in the fields of large and medium caliber, medium and low pressures in other industries.
