The three-piece flanged ball valve is widely used in many industries such as food, wine, beverage, dairy, fine chemical, pharmaceutical and biological engineering. The three-piece flanged ball valve is mainly made of stainless steel 304 and 316. It can also be customized according to customer requirements or according to the corrosive strength of the medium. It has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to 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 ball valve is widely used plastic, which has good sealing performance and has been widely used in vacuum system.

4. Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control.

5. It is easy to maintain, the structure of the ball valve is simple, the sealing ring is generally movable, and it is more convenient 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 sealing surface of the valve will not be eroded when the medium passes through.

7. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure. This type of valve should generally be installed horizontally in the pipeline.
