PFA Ball Valve (DIN-ANSI)- Stainless Steel

Reliable & Corrosion-Resistant Flow Control

The Spheron9 PFA/Teflon Lined Ball Valve (DIN/ANSI) is tailored for high-sterile conditions where precision, durability, and cleanliness are paramount. This valve features a stainless steel body (DIN 1.4116) with a polished surface that can be enhanced with electro-polishing for even greater smoothness and sanitation. The internal virgin PFA lining ensures chemical resistance and a flushable design with no dead spaces. Its full bore allows for high Cv values while maintaining efficiency. The one-piece ball-stem design ensures reliable actuation, and the blow-out safe shaft guarantees long-term, maintenance-free performance, ideal for cleanroom settings.
