Pneumatic Lined Regulated Butterfly Valve

The Pneumatic Lined Regulated Butterfly Valve consists of a pneumatic piston actuator and a PTFE-sealed butterfly valve, suitable for corrosive-demanding working conditions with temperatures up to 160°C. The valve adopts thick polymer lining technology on all fluid-contact components (valve body, disc, and stem), demonstrating excellent corrosion resistance and compatibility with any concentration of acids, alkalis, salts, oxidizers, reducing agents, and organic solvents. As an ideal product for shut-off and regulation in pipelines and containers handling gases, liquids, and semi-fluids, it is widely used in chemical, petroleum, pharmaceutical, food, steel smelting, paper-making, and hydropower systems. The fully lined PTFE and FEP  butterfly valve offers superior corrosion resistance, zero leakage, and extended service life. This corrosion-resistant butterfly valve is particularly suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids and other highly corrosive media.
