The Ductile Iron Dual Plate Wafer Check Valve is a high-performance, spring-loaded non-return valve designed to prevent backflow in piping systems. Featuring a compact wafer-style body made from durable ductile iron (GGG40/50 or equivalent), this valve offers superior strength, corrosion resistance, and longevity compared to traditional cast iron designs.
Key features include:
Dual spring-loaded plates for quick closure and minimal water hammer
Low pressure drop with excellent flow efficiency
Retainerless design for enhanced integrity and no external leakage
Suitable for horizontal or vertical installation
EPDM or NBR seats for tight sealing in water, oil, gas, and general industrial applications
Advantages over swing check valves: lighter weight, smaller face-to-face dimensions, reduced slamming, and easier installation between flanges (PN10/16/25 or ANSI Class 150/300).
Ideal for HVAC, water treatment, firefighting systems, petroleum, and chemical processing. Available in sizes from 2" to 48". Contact us for custom options and competitive pricing on high-quality ductile iron dual plate check valves.
