Product Description
The Aluminum Bronze Disc PTFE Seat Lug Butterfly Valve with Gear Operator is designed for on-off isolation in pipeline systems handling corrosive or chemically aggressive media. The aluminum bronze disc offers superior resistance to seawater and harsh environments, while the PTFE seat provides stable sealing performance and low operating friction, making it suitable for applications where elastomer seats may not be appropriate.
This Aluminum Bronze Disc PTFE Seat Lug Butterfly Valve with Gear Operator features a lug-type body that allows secure bolting and supports end-of-line service where required. The gear operator ensures smooth and controlled manual operation, especially in medium and large diameters where torque reduction is necessary. Typical applications include marine installations, chemical processing systems, cooling water lines, and industrial water treatment pipelines requiring dependable isolation rather than flow regulation.
