Pneumatic ball valves evolved from plug valves. Unlike plug valves, which rotate 90 degrees, the plug body is a spherical body with a circular through-hole or channel passing through its axis. Its working principle is to open or close the valve by rotating the valve core.

Pneumatic ball valve switches are lightweight, small in size, can be made into large diameters, reliable in sealing, simple in structure, and easy to maintain. The sealing surface and spherical surface are often in a closed state and are not easily corroded by the medium, and have been widely used in multiple industries.

Pneumatic ball valves and plug valves are the same type of valve, with only the closing part being a sphere that rotates around the centerline of the valve body to open and close the valve. Pneumatic ball valves are mainly used for pipelines, cutting speed, distribution, and changing the flow direction of media.

Advantages of Pneumatic Ball Valve

1. The fluid resistance is small, and the resistance coefficient is equal to the length of the same pipe section.

2. Simple structure, small size, and light weight.

3. Ball valve sealing surface materials are widely used in plastic products, with good sealing performance, and are widely used in vacuum systems.

4. This utility model is easy to operate, has a fast opening and closing speed, and only rotates 90 degrees from fully open to fully closed, making it convenient for remote control.

5. Easy maintenance, simple structure of pneumatic ball valve, movable sealing ring, and more convenient disassembly and replacement.

6. When the steel ball and valve seat are opened or closed, the sealing surface of the steel ball and valve seat is isolated from the medium. When the medium passes through, the sealing surface of the valve will not wear out.

7. It has a wide range of applications, with paths ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.

8. The power source of pneumatic ball valves is gas, generally at a pressure of 0.2~0.8MPa, which is relatively safe. If a pneumatic ball valve leaks, compared to hydraulic or electric valves, the gas can be directly discharged without polluting the environment and has high safety.

9. Compared with manual and turbine ball valves, pneumatic ball valves can be configured with larger diameters (manual and turbine ball valves are generally smaller than DN300 diameter, while pneumatic ball valves can currently reach DN1200 diameter).
