Cast Iron Dual Plate Wafer Check Valve PRODUCT CODE - ART 136

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

Manufactured from robust ductile iron, the valve offers excellent mechanical strength, impact resistance and long‑term durability — ideal 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.
