The imported pneumatic cage-type single-seat control valve adopts a fluid pressure unbalanced spool structure and a valve cover top-guided valve internal component form. It has a small volume, a simple structure, high adjustment accuracy, and good valve seat sealing performance. The parts of the valve in contact with the medium are made by high-pressure injection molding process, lined with corrosion-resistant and aging-resistant perfluoropropyl vinyl ether (referred to as F46), and sealed with polytetrafluoroethylene bellows. It not only has the unique advantages of being resistant to strong corrosive media such as acid (hydrochloric acid, sulfuric acid, hydrofluoric acid), alkali, but also has reliable sealing performance. It is suitable for regulating media that are strong acid, strong alkali, volatile, and permeable. Therefore, it is widely used in the control systems of special media in industrial automation devices such as chemical, petroleum, metallurgy, medicine, and textile.
