Product Description
The Ductile Iron Disc EPDM Seat Lug Butterfly Valve with Gear Operator is designed for on-off isolation in water and general industrial pipeline systems. The ductile iron disc provides good mechanical strength and cost-effective durability, while the EPDM seat ensures reliable sealing performance for clean water, wastewater, and other non-aggressive media. This configuration is widely used where stable shut-off and long service life are required.
This Ductile Iron Disc EPDM 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 enables smooth and controlled manual operation, especially in medium and large diameters where operating torque needs to be reduced. Typical applications include water supply networks, HVAC systems, wastewater treatment pipelines, and building services where dependable isolation is required rather than flow regulation.
