The working principle of pneumatic stainless steel ball valve is to make the valve open or blocked by rotating the valve.
Ball valve switch is light, small size, can be made into a large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and sphere are often closed, not easy to be eroded by the medium, and have been widely used in various industries.
Ball valve and plug valve are the same type of valve, only its closure is a sphere, the sphere rotates around the center-line of the valve body to open and close.
The 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 which has been 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 the pipe of the same length.
2. The utility model has the advantages of simple structure, small size and light weight.
3. Tight and reliable, the sealing surface material of ball valve is widely used in plastic, good sealing, and has been widely used in vacuum system.
4. Easy to operate, quick to open and close, from full open to full off as long as the rotation of 90 °, convenient for long-distance control.
5. The utility model has the advantages of convenient maintenance, simple structure of ball valve, movable sealing ring and convenient dis-assembly and replacement.
6. When fully open or closed, the sealing surface of the sphere and seat is isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
7. A wide range of applications, small to a few millimeters, large to a few meters, from high vacuum to high pressure can be used.
Ball valve has been widely used in petroleum, chemical industry, power generation, paper-making, atomic energy, aviation, rocket and other departments, as well as in people's daily life.
