Main features: The main characteristics of the ball valve are its compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in a closed state, not easy to be washed away by the medium, easy to operate and maintain, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries. Ball valve body can be integral, can also be combined.

Ball valve is not only simple structure, good sealing performance, and in a certain nominal diameter range of small size, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easy to achieve rapid opening and closing, is one of the fastest developing valve varieties in recent decades. Ball valve is evolved from the plug valve, its opening and closing parts as a sphere, using the sphere around the axis of the valve stem rotated 90° to achieve the purpose of opening and closing. Ball valve in the pipeline is mainly used to cut off, distribute and change the direction of the flow of the medium, designed into the V-shaped opening ball valve also has a good flow regulation function.

Especially in the United States, Japan, Germany, France, Italy, the West, the United Kingdom and other industrial development, the use of ball valves is very wide, the variety and number of use is still continuing to expand, and to high temperature, high pressure, large caliber, high sealing, long life, excellent adjustment performance and a valve multi-function direction. Its reliability and other performance indicators have reached a high level, and has partially replaced the gate valve, globe valve, throttle valve. With the technological progress of ball valves, in a foreseeable short period of time, especially in oil and gas pipelines, refinery cracking units and the nuclear industry will have a wider range of applications. In addition, in other industries in large and medium-sized caliber, low and medium pressure areas, ball valves will also become the dominant valve type .

Advantages:

1. The fluid resistance is small, and the full-diameter ball valve has basically no flow resistance.

2. Simple structure, small size, light weight.

3. Tight and reliable. It has two sealing surfaces, and the sealing surface material of the ball valve is widely used in various plastics, which has good sealing property and can achieve complete sealing. It has also been widely used in vacuum systems.

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.

Seven. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.

8. Because the ball valve has wipeability during opening and closing, it can be used in media with suspended solid particles.
