Product Description
The SS316 Disc PTFE Seat Lug Butterfly Valve with Gear Operator is designed for on-off isolation in water and industrial pipeline systems where corrosion resistance and chemical compatibility are required. The SS316 stainless steel disc provides enhanced resistance to corrosive media, while the PTFE seat ensures stable sealing performance and low operating friction, especially in applications where elastomer seats may be unsuitable.
This SS316 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 where required. The gear operator enables smooth and controlled manual operation, particularly in medium and large diameters where operating torque needs to be reduced. Typical applications include chemical processing lines, seawater and cooling water systems, industrial water treatment, and other services requiring dependable isolation rather than flow regulation.
