The Ductile Iron Foot Valve QT450-10 is a robust and reliable check valve designed for installation at the bottom of suction pipes in water pump systems. Made from high-grade QT450-10 ductile iron (also known as GGG40 equivalent), this foot valve features excellent toughness, high plasticity, and superior corrosion resistance compared to traditional cast iron.
Key features include:
Built-in stainless steel or bronze strainer to prevent debris from entering the pump, ensuring long-term protection and smooth operation.
One-way flow design that allows water to enter while preventing backflow, maintaining pump prime and avoiding dry running.
Flanged ends for easy and secure installation (available in PN10/PN16 or ANSI Class 150 standards).
Epoxy coating option for enhanced durability in harsh environments, suitable for clean water, sewage, irrigation, and industrial applications.
Silent operation with minimal head loss, ideal for municipal water supply, agriculture, and pumping stations.
This energy-saving valve offers outstanding mechanical properties with tensile strength ≥450 MPa, elongation ≥10%, and good low-temperature impact resistance. It ensures reliable performance, reduces maintenance costs, and extends pump lifespan.
