A ball valve is a valve in which the opening and closing element (the ball) is driven by the valve stem and rotates around the stem axis. It is widely used in industries such as petroleum refining, long-distance pipelines, chemicals, and papermaking. It primarily serves to shut off or connect pipeline media and also provides fluid regulation.

1. Low fluid resistance: A full-bore ball valve has virtually no flow resistance.
2. Simple structure, compact size, and light weight.
3. Tight and reliable. Ball valves have two sealing surfaces, and various plastics are widely used for these surfaces, ensuring excellent sealing and a complete seal. They are also widely used in vacuum systems.
4. Easy to operate, opening and closing quickly. A simple 90° rotation from fully open to fully closed facilitates remote control.
5. Easy maintenance: Ball valves have a simple structure, and the sealing ring is generally removable, making them easy to disassemble and replace.
6. When fully open or fully closed, the sealing surfaces between the ball and the valve seat are isolated from the media, preventing erosion of the valve sealing surfaces when the media passes through.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used in applications from high vacuum to high pressure.
8. Because ball valves have a wiping effect during opening and closing, they can be used in media containing suspended solid particles.
