The working principle of the pneumatic ball valve is to make the valve unblocked or blocked by rotating the valve core. Pneumatic ball valve switch is light, small 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 following pneumatic ball valve manufacturers will introduce its basic characteristics to you: 1. Simple structure, small size and light weight. 2. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. 3. 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. 4. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure. 5. The maintenance is convenient, the pneumatic ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace. 6. 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. 7. 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. 8. 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 diameter, and pneumatic ball valves can currently reach DN1200 diameter.) 9. Because the power source of pneumatic ball valves adopts It is a gas, generally 0.2-0.8MPa pressure, which is relatively safe. If the pneumatic ball valve leaks, compared with hydraulic and electric, the gas can be discharged directly, which does not pollute the environment and has high safety.
