Ductile Iron Rubber Seated Butterfly Valve – NPS 2" to 48", Class 150–2500

This ductile iron rubber seated butterfly valve offers reliable flow control for industrial and commercial systems, featuring a concentric disc design with an EPDM-lined seat for superior sealing and durability. Available in sizes from NPS 2” to 48” and pressure classes from Class 150 to Class 2500, the valve is engineered for performance in harsh environments with temperature ranges between -20°C and 200°C (-4°F to 392°F). The wafer-type construction allows easy installation between standard flanges, reducing installation footprint and costs.

Manufactured in compliance with API 609, AWWA C504, and ASME B16.34 standards, this valve is constructed from premium ductile iron with options in cast steel, stainless steel, and high-alloy materials for specialized applications. Its versatile compatibility and robust construction make it ideal for use in water supply, HVAC, power generation, chemical processing, and general industrial applications.
