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

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

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

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

2, simple structure, small size, light weight.

3, close and reliable, at present the ball valve sealing surface material widely used plastic, good sealing, vacuum system has 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, easy maintenance, pneumatic ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.

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

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