Pneumatic ball valves are mainly used in pipelines for fast cutting speed, distribution, and changing the flow direction of the medium. The working principle of pneumatic ball valves is to rotate the valve core to make the valve unobstructed or blocked. Pneumatic ball valves are lightweight, small in size, and can be made into large diameters. They have reliable sealing, simple structure, and convenient maintenance. The sealing surface and spherical surface are often in a closed state and are not easily eroded by media. They are widely used in various industries.
