Acid-Resistant PP Ball Valve

Metal valves and fittings cannot be used in highly corrosive acidic environments because aggressive fluids such as sulfuric acid, citric acid, hydrochloric acid or other chemicals will rapidly destroy them. In these conditions, the Vispar Acid-Resistant PP Ball Valve is the ideal solution. Manufactured entirely from premium-grade polypropylene (PP), it offers outstanding chemical resistance far superior to any metal valve. Vispar is one of the most trusted Iranian manufacturers of industrial-grade polymeric valves, including this acid-proof ball valve series. Acid-Resistant PP Ball Valve The Vispar Acid-Resistant PP Ball Valve is a true-union (double-union) full-port ball valve specially developed for corrosive and aggressive fluids. Both ends feature union connections, allowing the valve body to be removed from the pipeline in seconds for cleaning, inspection or replacement – without cutting the pipe. The red handle clearly identifies it as “acid/chemical service”. Technical Specifications – Vispar Acid-Resistant PP Ball Valve Body & unions material: : Solid polypropylene (PP) Pressure rating : PN10 (10 bar at 20 °C) Sizes : 20 mm – 110 mm (¾” – 4″) Connection type : Solvent-weld (socket) unions on both sides Seat & seals : PTFE seats + EPDM or FKM (Viton) O-rings (optional) Handle : Red acid-resistant lever Full-port design → negligible pressure drop Excellent UV and weather resistance 100 % corrosion-proof even in the most aggressive chemicals Fast and easy maintenance – valve body removable in seconds Applications Chemical process lines (acids, alkalis, salts) Fertilizer and pesticide plants Water treatment & desalination (chlorine, ozone, acids) Electroplating and metal finishing Pharmaceutical and food-grade acid lines Mining and mineral processing Any pipeline carrying aggressive or corrosive fluids Key Advantages True-union design → fastest installation and service Completely immune to corrosion – lifetime many times longer than metal valves Lightweight (1/7th the weight of stainless steel) Perfect sealing and zero leakage even after thousands of cycles Red handle for immediate visual identification in chemical plants Very competitive price compared with PVDF, PTFE or stainless valves Installation Note Connections are solvent-weld (glue) type – same method as standard PP piping. Heat the pipe end and the valve socket with a PP welding equipment and push together for a permanent, leak-free joint.
