Product Description
The Ductile Iron Disc EPDM Seat Wafer Butterfly Valve with Handle is designed for on-off isolation in water and general industrial pipeline systems. The ductile iron disc provides sufficient mechanical strength and durability, while the EPDM seat ensures reliable sealing performance for clean water, wastewater, and non-aggressive media. This configuration is commonly selected for cost-effective and stable shut-off applications.
This Ductile Iron Disc EPDM Seat Wafer Butterfly Valve with Handle features a compact wafer-type body for easy installation between flanges. Manual handle operation allows quick opening and closing, making the valve 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.
