Product Overview
The KOZO Super Duplex Swing Check Valve is designed for offshore, seawater and chloride-containing process systems requiring automatic backflow prevention and super duplex metallurgy.
Material Options
Forged components may use ASTM A182 F53 / UNS S32750, while cast pressure parts may use ASTM A890 Grade 5A or another approved super duplex grade. The exact material designation must match the component form and project requirement.
Key Design Features
- Super duplex pressure-containing construction.
- Swing-disc automatic non-return operation.
- Flanged or butt-weld connection options.
- Project-specific hinge, shaft, disc and seat materials.
