High Platform Stainless Steel Pneumatic Ball Valve

The working principle of pneumatic ball valves is to rotate the valve core to make the valve unobstructed or blocked. Pneumatic ball valve switches are lightweight, small in size, can be made into large diameters, reliable in sealing, simple in structure, easy to maintain, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium. They are widely used in various industries.

Pneumatic ball valves and plug valves belong to the same type of valve, except that their closing element is a ball that rotates around the centerline of the valve body to achieve opening and closing.

Pneumatic ball valves are mainly used in pipelines for fast cutting speed, distribution, and changing the flow direction of media.

Pneumatic ball valve is a new type of valve that has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.
2. Simple structure, small size, and light weight.
3. Tight and reliable, the sealing surface material of ball valves is widely made of plastic, with good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.
5. Easy to maintain, pneumatic ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement relatively convenient.
When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.
8. Because the power source of pneumatic ball valves is gas, usually at a pressure of 0.2-0.8MPa, it 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 it has higher safety.
Compared to manual and turbine ball valves, pneumatic ball valves can be configured with larger diameters (manual and turbine ball valves are generally below DN300 diameter, while pneumatic ball valves can reach DN1200 diameter)
Pneumatic ball valves have been widely used in various sectors such as petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets, as well as in people’s daily lives.
