     According to the ball valve and pipe connection can be divided into flange connection ball valve, internal thread and external ball connection ball valve and welded ball valve, now their characteristics and uses are described below.

1 , flange connection ball valve according to its flange structure type, there are integral flange, threaded flange, welded flange ball valve and the clamp type ( flange ) connection ball valve points. Due to its simple structure, convenient manufacture, reliable use and wide application range, the flange is widely used.

2 , the threaded flange is connected to the ball valve, the valve's connecting flange and valve body are made separately, and the screw thread is connected with the valve body. The ball valve structure not only has the advantages of integral flange connection, but also can reduce the blank size and weight of the left and right halves of a body, which is convenient for processing and manufacturing, and is particularly advantageous for a forged valve body for a high-pressure pvdf ball valve. This connection is particularly suitable for corrosive media applications.

     3 , welded flange ball valve and threaded flange connection ball valve similar to the connection flange and valve body using split hair also, to be completed after the mechanical processing, the welding method to the flange welded to the valve body. It is designed to reduce the weight of the valve body casting and is easy to manufacture. Different from this, this valve is suitable for large-diameter applications.
