The Pneumatic Flange Ball Valve Series is engineered for rapid and reliable flow control using a floating ball design and pneumatic actuation. With a size range of DN15 to DN300 and support for pressure classes up to 600Lb and 20K, this series is suitable for a wide variety of fluids and gases. The valves are available in carbon steel (WCB) and stainless steel (CF8, CF8M, CF3, CF3M) body materials, with seat options such as PTFE, PPL, and high-temperature variants (N, H, Y). Designed according to GB, ANSI, and JIS standards, and compatible with both ON/OFF and regulating control, these valves are ideal for modern automated systems requiring safety, speed, and precision.
