Ductile Iron Dual Plate Wafer Check Valve PRODUCT CODE - ART 121

Ductile Iron Dual Plate Wafer Check Valves provide a compact, high‑strength and reliable solution for preventing reverse flow in water, HVAC, fire‑protection and general industrial systems. Their dual‑plate (or “double‑door”) design uses two spring‑loaded plates that open easily under forward flow and close rapidly when the flow stops or reverses, delivering fast, dependable backflow protection.

Manufactured from robust ductile iron, these valves offer excellent mechanical strength, impact resistance and long‑term durability, making them suitable for medium‑ to large‑scale installations. The wafer‑style body fits neatly between flanges, reducing weight and installation space while maintaining strong structural integrity.

The spring‑assisted plates ensure smooth operation with minimal pressure loss, while the central hinge mechanism provides consistent sealing performance. Many models include an epoxy‑coated body for enhanced corrosion resistance, supporting long service life even in demanding environments.
