Ball valves and plug valves belong to the same type of valve, the difference is that its closing part is a ball, ball rotating about the center line of the body to open and close a valve.The ball valve in the pipeline is mainly used to cut off, distribution and change the flow direction of the medium.Ball valve is a new type of valve widely used in recent years, it has the following advantages: 1. Fluid resistance is small, its resistance coefficient and the same length of the pipe section is equal.2.Simple structure, small size and light weight.3.Compact and reliable, the ball valve sealing surface material is widely used in plastic, good sealing, in the vacuum system has also been widely used.4.Easy to operate, fast open and close, from full open to full close only rotation 90°, convenient for remote control.5.Easy maintenance, simple ball valve structure, sealing ring is generally active, disassembly and replacement are relatively convenient.6.When fully open or fully closed, the sealing surface of the ball and seat is isolated from the media, which will not cause erosion of the valve sealing surface when passing through.7.Wide range of applications, sizes from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
