Product Description
The Aluminum Bronze Disc EPDM Seat Lug Butterfly Valve with Gear Operator is designed for on-off isolation in water and industrial pipeline systems where corrosion resistance and stable sealing are required. The aluminum bronze disc offers improved resistance to seawater and corrosive media compared with standard ductile iron materials, while the EPDM seat provides reliable sealing performance for clean water, wastewater, and non-aggressive fluids.
This Aluminum Bronze Disc EPDM 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 water supply networks, cooling water systems, marine-related installations, and general industrial pipelines where dependable isolation is required rather than flow regulation.
