Product Description
The SS316 Disc PTFE Seat Lug Butterfly Valve with Handle is designed for manual on-off isolation in pipeline systems where corrosion resistance and chemical compatibility are required. The SS316 stainless steel disc provides enhanced resistance to aggressive media, while the PTFE seat ensures stable sealing performance and low operating friction in applications where rubber seats may not be suitable.
This SS316 Disc PTFE Seat Lug Butterfly Valve with Handle features a lug-type body that allows secure bolting to the pipeline and supports end-of-line service when required. Manual handle operation enables quick and direct control, making it suitable for small to medium pipe sizes in chemical processing lines, marine systems, cooling water networks, and industrial water treatment applications where dependable isolation is required rather than flow regulation.
