Stainless steel ball valves only need to rotate 90 degrees of operation and a small torque to close tight. The completely equal body cavity provides the medium with little resistance and a straight flow path. The main feature of the ball valve is its compact structure, easy operation and maintenance, stainless steel ball valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Ball valve body can be integral, can also be combined. This type of valve should generally be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve material is divided into 304,316,321 stainless steel ball valve.

The advantages of stainless steel ball valve
1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length.
2. Simple structure, small size, light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastic, good sealing, and has been widely used in the vacuum system.
4. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control.
5. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when it passes through.
7. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
Ball valve has been widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rockets and so on
