Pneumatic three piece ball valves and plug valves belong to a type of valve, only its closing piece is a sphere, the ball revolves around the center line of the valve to achieve the opening and closing of a valve.

Pneumatic three piece ball valve in the pipeline is mainly used to do cutting speed, distribution and change the direction of flow medium.

Pneumatic three piece ball valve is a new type of valve widely used in recent years. It has the following advantages:

1. pneumatic three piece ball valve, fluid resistance is small, and its resistance coefficient and the same length of the pipe section.

2. simple structure, small size, light weight.

3. close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.

4. pneumatic three ball valve has the advantages of convenient operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.

5., maintenance is convenient, pneumatic ball valve structure simple, sealing ring is generally active, disassembly and replacement are more convenient.

6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.

7. pneumatic three piece ball valve for a wide range of diameter from small to a few millimeters, large to several meters, from high vacuum, high pressure can be applied
