A pneumatic ball valve is a commonly used control element. It is evolved from a plug valve and has the same 90-degree rotation. The difference is that the plug body is a sphere with a circular through a hole or channel passing through its axis. The following mainly introduces the use and advantages of pneumatic actuated ball valves, hoping to help you use the product better.

The Use of The Pneumatic Ball Valve

The working principle of the air actuated ball valve is to make the valve unblocked or blocked by rotating the valve core. On-off ball valve with pneumatic actuator switch is light, small, and can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often closed, not easily eroded by the medium, and it is widely used in various industries.


Air operated ball valve and plug valve belong to the same type of valve. Only its closing part is a ball. The ball rotates around the centerline of the valve body to achieve opening and closing.


Pneumatic ball valves are mainly used in the pipeline to cut off fast, distribute and change the flow direction of the medium.

Advantages of The Pneumatic Ball Valve

1. The fluid resistance of the pneumatic actuated ball valve is small, and its resistance coefficient is equal to that of a pipe section of the same length.


2. The pneumatic ball valve has a simple structure, small size, and lightweight.


3. The full port ball valve is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics, with good sealing performance, and has been widely used in vacuum systems.


4. The pneumatic ball valve is easy to operate as well as open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.


5. Pneumatic SS ball valves are easy to maintain. The structure of the pneumatic ball valve is simple. The sealing ring is generally movable and it is convenient to disassemble and replace.


6. When fully open or fully closed, the sealing surface of the ball and the valve seat are isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface.


7. The pneumatic ball valve has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.


8. Because the pneumatic ball valve power source uses gas, the pressure is generally 0.2-0.8MPa, which is relatively safe. If the pneumatic ball valve leaks, compared with hydraulic and electric, gas can be discharged directly, which does not pollute the environment and has high safety.


9. Compared with manual and turbine rotating ball valves, pneumatic ball valves can be configured with large diameters. (Manual and turbine rotating ball valves are generally below DN300, while pneumatic ball valves can currently reach DN1200.)



Pneumatic metal seated ball valves have been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets, and other departments, as well as people's daily lives.
