Designed for high‑volume mainlines and critical fluid handling, the CVCSWDPV600X 6‑inch dual‑plate wafer check valve delivers rapid, reliable shut‑off to prevent backflow surges. Its split‑disc, spring‑loaded dual‑plate mechanism engages instantly, ensuring a tight seal against reverse flow while maintaining low pressure drop during normal operation.

Built with a cast ductile iron body, the valve offers exceptional strength and durability for municipal water systems, industrial cooling lines, and commercial HVAC applications. The precision‑machined stainless‑steel disc and FKM elastomer seat provide long‑term resistance to corrosion and chemical attack, making it ideal for aggressive media. The compact wafer footprint keeps the face‑to‑face length short, reducing pipe stress and installation weight compared to conventional swing check valves.

Compatible with standard 6‑inch ANSI B16.5 Class 150 flanges, this valve is ready for direct wafer mounting, simplifying installation and maintenance in demanding infrastructure projects.
