Three piece ball valve and gate valve belong to the same type of valve. The difference is that its closing part is a ball. The ball rotates around the center line of the valve body to open and close the valve. Three piece ball valve is mainly used to cut off, distribute and change the flow direction of medium in pipeline.

Three piece ball valve has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length of pipe.
2. Simple structure, small volume and light weight.
3. It is tight and reliable. The sealing surface material of ball valve is widely made of plastic and has good sealing performance. It has also been widely used in vacuum system.
4. Convenient operation, fast opening and closing, from full opening to full closing as long as 90 ° rotation, convenient for remote control.
5. Easy maintenance, simple structure of ball valve, movable sealing ring, easy disassembly and replacement.
6. When the valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause the erosion of the valve sealing surface.
7. Wide range of application, diameter from small to several millimeters, to several meters, from high vacuum to high pressure can be applied. Flange ball valve, flange gate valve, knife gate valve.
