Product Description
The Ductile Iron Disc EPDM Seat Lug Butterfly Valve with Handle 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 non-aggressive media. This configuration is widely used in applications where stable shut-off and ease of maintenance are required.
This Ductile Iron Disc EPDM Seat Lug Butterfly Valve with Handle features a lug-type body that allows secure bolting to the pipeline and supports end-of-line service where required. Manual handle operation enables quick and straightforward valve control, making it suitable for small to medium pipe sizes in water supply networks, HVAC systems, and building services where dependable isolation is required rather than flow regulation.
