PTFE lined centric butterfly valve for corrosive fluids and high-purity applications. Designed and manufactured for over 20 years in Switzerland, Bianca is built for long-lasting use in highly demanding media and environments up to 16 bar. The extremely versatile and reliable butterfly valve is available with a ductile iron body and a stainless steel body as wafer, lug or U-section body type. Thanks to the range of conductive disc and liner materials, it can also be used in explosive environments. High-purity, LABS-free and ATEX versions are available. Liner materials: PTFE, PTFE conductive, Ultraflon®, Ultraflon® conductive, UltraleneTM Disc materials: PFA, PFA conductive, Stainless steel, Hastelloy, Duplex, the full metal discs available mechanically polished Ra < 0.8, Stainless steel electro polished Ra < 0.4 / Fe < 1% Technical Specifications Market segments •Water •Water Treatment Plants •Power Generation •Chemical Processing •Oil & Gas •Marine •Life Science •Mining/Slurry •Bulk Handling •Air Separation •Steel Industry Body material Metal Body type •Wafer •Lug •U-section Connection end •Flanged Tightness Bi-directional Temperature range (+/–) •-20 – +200 °C Working pressure (max.) 2.5bar 6bar 10bar 16bar Nominal diameter (DN) •32 mm / 1¼″ •40 mm / 1½″ •50 mm / 2″ •65 mm / 2½″ •80 mm / 3″ •100 mm / 4″ •125 mm / 5″ •150 mm / 6″ •200 mm / 8″ •250 mm / 10″ •300 mm / 12″ •350 mm / 14″ •400 mm / 16″ •450 mm / 18″ •500 mm / 20″ •600 mm / 24″ •700 mm / 28″ •750 mm / 30″ •800 mm / 32″ •900 mm / 36″
