The pneumatic threaded angle valve is an angle seat valve controlled by an air actuator. It adopts a threaded (internal thread) connection method and features a compact structure and high flow rate. It is widely used in the industrial field. Here is a detailed introduction: • Working principle: The single-acting pneumatic threaded angle seat valve operates by spring return to achieve opening and closing, and it is divided into the normally open type and the normally closed type; the double-acting angle seat valve is controlled to open and close by compressed gas. • Structural features: Usually adopts a Y-shaped design, which enlarges the flow passage area of the valve chamber, making the fluid flow more smoothly and the flow rate larger than that of ordinary stop valves. The valve stem is mostly made of 316L stainless steel, and the seal uses wedge-shaped PTFE. It has the features of automatic correction, automatic lubrication, and maintenance-free. • Main parameters: The nominal diameter is generally between DN10 and DN100, the nominal pressure is between PN16 and PN25, the valve body material is mostly CF8M, CF8 and other stainless steel materials, the sealing material is commonly polytetrafluoroethylene, and the applicable media include water, neutral gases and liquids, alcohol, oil, etc. The medium temperature varies depending on the sealing material, generally ranging from -20℃ to 180℃. • Application fields: Widely applied in various industries such as filling equipment, beer and beverage production, textile printing and dyeing, medical devices, biopharmaceuticals, disinfection and sterilization, and food industry. • Installation and Maintenance: The pipeline must be clean and free from contamination. It should be installed as needed, but try to position the actuator upwards and pay attention to the flow direction. Before opening or repairing this angle valve, first cut off the fluid and control air source and reduce the pressure in the pipeline system.
