summary:

American standard pneumatic ball valves are mainly used in pipelines for fast cutting speed, distribution, and changing the flow direction of media. Pneumatic ball valve is the most widely used new type of valve in recent years, with the following advantages: low fluid resistance, and its resistance coefficient is equal to that of a pipe section of the same length. Simple structure, small size, and light weight. 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. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control. Easy to maintain, the 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. Pneumatic valves have 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. Widely used in various sectors such as petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets, as well as in daily life.
