The working principle of stainless steel valve is to make the valve unblocked or blocked by rotating the valve. Pneumatic ball valve switch is light, small in size, can be made into large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often closed, not easy to be eroded by medium, and are widely used in various industries. The main advantages of stainless steel valves.

1. The fluid resistance is small, and its resistance coefficient is equal to that of the 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 ball valve is widely used plastic, which has good sealing performance, and has also been widely used in vacuum system.
4. Easy to operate, quick to open and close, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
7. It has a wide range of applications, with diameters ranging from small to several millimeters to several meters, and can be applied from high vacuum to high pressure. When the ball rotates 90 degrees, it should be spherical at the entrance and exit to cut off the flow.
