Product Description
The SS304 Disc PTFE Seat Lug Butterfly Valve with Gear Operator is designed for on-off isolation in pipeline systems where corrosion resistance and stable sealing are required. The SS304 stainless steel disc provides dependable resistance to common industrial media, while the PTFE seat ensures consistent sealing performance and low operating friction, particularly in applications where elastomer seats may not be suitable.
This SS304 Disc PTFE Seat Lug Butterfly Valve with Gear Operator features a lug-type body that allows secure bolting to the pipeline and supports end-of-line service when required. The gear operator enables smooth and controlled manual operation, especially in medium and large diameters where operating torque needs to be reduced. Typical applications include chemical processing lines, water treatment systems, cooling water networks, and general industrial pipelines requiring reliable isolation rather than flow regulation.
