Butterfly Valves / Metal Body / PTFE Lined
Butterfly valve DN 32-900

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%


Designed and built for shutoff and control of aggressive and corrosive fluids, as well as high purity applications.

Chemical Processing

Reliability and safety in demanding applications such as production, distribution and surface treatment.

Life Science

Safety, high purity and sterility are paramount when it comes to applications within the Life Sciences segment.

Steel Industry

Ideal for highly corrosive processes where only a Fluoroplastic lined butterfly valve can be used, such as in pickling lines.

Mining Bianca for the mining industry covers applications such as acid and solvent extraction of metals and aggressive slurries.

High Purity

High purity are used where absolute purity is essential and the smallest impurities have to be avoided, such as in the semiconductor industry.


The combination of highly aggressive acids at high temperatures requires the use of a Bianca Fluoroplastic lined butterfly valve for the production of bioethanol

Food and Beverage

Where non-adhesive characteristics and the highest purity are critical, we use standard valve components approved according to FDA 177.1550 and EU 10/2011.
