Ductile Iron Tilting Butterfly Check Valve

Discover the superior flow control solution with our high-performance Ductile Iron Tilting Butterfly Check Valve. Engineered for demanding industrial applications, this valve is designed to prevent backflow efficiently and reliably. For applications requiring a specific disc design, our Tilting Disc Check Valve offers exceptional sealing. In systems where hydraulic actuation is not desired, the Non-hydraulic Tilting Butterfly Check Valve provides a purely mechanical, maintenance-friendly alternative. For installations requiring manual override or positioning control, consider our robust Manual Tilting Butterfly Check Valve. Furthermore, our space-saving Wafer Tilting Butterfly Check Valve is an excellent choice for compact piping layouts, installed between flanges without the need for additional nuts or bolts.


The Ductile Iron Tilting Butterfly Check Valve represents a significant advancement in check valve technology. Its unique tilting disc mechanism ensures swift, low-resistance opening with forward flow and immediate, positive sealing upon flow reversal, minimizing water hammer and pressure surge. The disc's offset pivot point and weighted design allow it to respond rapidly to changing flow conditions, providing silent operation and enhanced durability. Constructed from high-grade ductile iron, the valve body offers exceptional strength and impact resistance, making it suitable for a wide range of pressures and corrosive environments. This design is particularly effective in horizontal pipelines for water, wastewater, seawater, and other fluid systems, ensuring reliable performance with minimal pressure drop and maintenance requirements over its extended service life.
