The pneumatic two-piece ball valve is mainly used in the pipeline to cut off the speed, distribute and change the flow direction of the medium. 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 of the pneumatic two-piece ball valve 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 the vacuum system.
4. The pneumatic two-piece ball valve is easy to operate and open and close quickly. It only needs 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. The sealing ring is generally movable, and it is convenient 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. When the medium passes, it will not cause erosion of the valve sealing surface.
7. The pneumatic two-piece ball valve has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.
