Pneumatic ball valve is a new type of valve that has been widely used in recent years. It has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.
2. Simple structure, small size and light weight.
3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in vacuum systems.
4. Convenient operation, rapid opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.
5. Convenient maintenance. The pneumatic ball valve has a simple structure, and the sealing ring is generally movable, making it easy to disassemble and replace.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. A wide range of applications, ranging from a small diameter to a few millimeters, as large as a few meters, and can be applied from high vacuum to high pressure
Pneumatic ball valves have been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily life.
