The Difference Between Plug Valve And Pneumatic Three-piece Ball Valve

Difference between plug valve and pneumatic three-piece ball valve

Pneumatic three-piece ball valve and plug valve are valves of the same type, except that its closing piece is a sphere, which rotates around the center line of the valve body to achieve opening and closing.

Pneumatic three-piece ball valve is mainly used in pipelines to cut off quickly, distribute and change the flow direction of the medium.

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

3 Piece Ball Valve

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

2. Simple structure, small size and light weight.

3. Tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastic, with good sealing performance, and has been widely used in vacuum systems.

4. The pneumatic three-piece ball valve is easy to operate and opens and closes quickly. It only needs to rotate 90° from full open to full closed, which is convenient for long-distance control.

5. Easy maintenance, the pneumatic ball valve has a simple structure, the sealing ring is generally movable, and it is 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 passing through.

7. The pneumatic three-piece ball valve has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.
