Ductile Iron Double Check Valve PRODUCT CODE - ART 237

Ductile Iron Double Check Valves provide a strong, durable and regulation‑compliant solution for preventing backflow in commercial, industrial and municipal water systems. Built from high‑strength ductile iron, these valves offer excellent resistance to pressure, impact and long‑term wear, making them ideal for demanding installations where reliability is essential.

The double‑check design incorporates two independent non‑return mechanisms, delivering a higher level of protection against reverse flow and contamination. Each check opens smoothly under forward flow and closes automatically if the flow stops or reverses, helping safeguard pipework, equipment and potable‑water supplies.

A tough epoxy‑coated body enhances corrosion resistance, while the internal components are engineered for smooth operation and long service life. Available in a range of sizes and flange configurations, ductile iron double check valves integrate easily into new or existing water‑supply networks.
