brief introduction
Three piece ball valve and gate valve belong to the same type of valve. The difference is that the closing part is a ball, and 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 section.
2. Simple structure, small volume and light weight.
3. It is tight and reliable. The sealing surface material of ball valve is widely used in plastic, with good sealing performance. It has also been widely used in vacuum system.
4. It is easy to operate and fast to open and close. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.
5. The maintenance is convenient, the ball valve structure is simple, the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When the valve is fully open or closed, the sealing surface of the ball and the valve seat shall be isolated from the medium. When the medium passes through, the corrosion of the valve sealing surface will not be caused.
7. It has a wide range of applications, ranging from small diameter to several millimeters and large diameter to several meters, from high vacuum to high pressure. Flange ball valve, flange gate valve, knife gate valve.
