Wafer & Lug CI DI Material Concentric Butterfly Valves are for performance in controlling the flow of liquids and gases. From BONNY VALVE, these valves are built to handle various pressure ratings and provide long-lasting durability, making these fit for a wide range of applications.

The valves are available in sizes ranging from 2” to 80” (DN50 to DN2000) and are constructed from materials such as cast iron, ductile iron, stainless steel, and other alloys. This ensures reliability even in challenging environments. The valve's concentric type design promotes smooth operation and reduces wear over time.
