Product Description
The Ductile Iron Disc EPDM Seat Wafer Butterfly Valve with Gear Operator is designed for reliable shut-off in water and low-pressure industrial pipeline systems. The ductile iron disc provides structural strength and cost-effective durability, while the EPDM seat delivers dependable sealing performance for clean water, HVAC, and general service media.
With its wafer-type body, this valve is installed between flanges to save space and reduce system weight. The gear operator ensures smooth and controlled opening and closing, especially in medium and large diameters where manual torque would otherwise be high.
The Ductile Iron Disc EPDM Seat Wafer Butterfly Valve with Gear Operator is typically selected for water supply lines, wastewater networks, cooling systems, and building services pipelines where stable isolation and simple maintenance are required.
