Product Description
The Ductile Iron Disc PTFE Seat Lug Butterfly Valve with Handle is designed for manual on-off isolation in pipeline systems where stable sealing and structural strength are required. The ductile iron disc provides reliable mechanical performance, while the PTFE seat ensures consistent sealing and improved chemical compatibility compared with standard rubber seats.
This Ductile Iron 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 necessary. Manual handle operation enables quick and direct valve control, making it suitable for small to medium pipe sizes in water treatment systems, cooling water networks, and general industrial applications where dependable isolation is required rather than flow regulation.
