The stainless steel Russian standard ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Ball valve is a new type of valve widely used in recent years, it has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.
2. Simple structure, small size and light weight.
3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in the vacuum system.
4. Convenient operation, fast opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.
5. Convenient maintenance, simple structure of the ball valve, generally movable sealing ring, easy 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. When the medium passes, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.

Stainless steel Russian standard ball valves have been widely used in petroleum, chemical, metallurgy, electric power, construction, heating, water supply and drainage, water treatment and other industries.
