Ductile Iron Double Check Valve PRODUCT CODE - ART 236

The ART 236 Ductile Iron Double Check Valve provides a heavy‑duty, regulation‑compliant solution for preventing backflow in commercial, industrial and municipal water systems. Built from high‑strength ductile iron, it delivers excellent resistance to pressure, impact and long‑term mechanical stress, making it ideal for demanding installations where reliability is essential.

The ART 236 features two independent non‑return check mechanisms, offering a higher level of protection than single‑check designs. Each check opens smoothly under forward flow and closes automatically if the flow stops or reverses, helping safeguard potable‑water supplies, pipework and downstream equipment from contamination or pressure surges.

A durable epoxy‑coated body enhances corrosion resistance, while the internal components are engineered for smooth operation and long service life. Available in a range of flanged sizes, the ART 236 integrates easily into new or existing water‑supply networks and is suitable for both horizontal and vertical installations (subject to manufacturer guidance).
