Lined valve

Pneumatic steel lined PTFE directional three-way flange ball valve is a high-performance valve designed for controlling strong corrosion, high temperature, and complex media, widely used in industrial fields such as chemical, petroleum, and pharmaceutical industries. The core structure adopts a stainless steel valve body lined with polytetrafluoroethylene (PTFE), which combines the excellent corrosion resistance of fluoroplastics (able to withstand strong acids, alkalis, and organic solvents) with the mechanical strength of the metal matrix to ensure the stability and long life of the valve under harsh working conditions. The three-way design is divided into T-shaped (diversion) or L-shaped (reversing) structures, which drive the sphere to rotate 90 ° through a pneumatic actuator to achieve flexible switching or flow distribution of the medium between the three ports, meeting the diverse needs of pipeline systems for diversion, merging, or flow direction switching. The flange connection method ensures the stability of installation, and the sealing surface adopts PTFE material or reinforced composite sealing structure, effectively preventing leakage and adapting to high pressure and high temperature (-196 ℃ to 200 ℃) environments. Pneumatic control supports remote automation operation, with fast response and precise positioning. It can be adapted to single acting (spring reset) or double acting actuators to meet the requirements of fault safety return or continuous adjustment. This valve has the characteristics of corrosion resistance, wear resistance, low flow resistance, and lightweight. It is particularly suitable for conveying corrosive media such as sulfuric acid, hydrochloric acid, and chlor alkali, as well as process flows in the pharmaceutical and food industries that require high cleanliness. It is a key equipment in modern chemical fluid control.
