Product Overview
The KOZO Super Duplex Gate Valve is designed for offshore, seawater and chloride-containing process systems where high strength and super duplex metallurgy are required for full-bore isolation.
Material Options
Forged components may use ASTM A182 F53 / UNS S32750, while cast bodies may use ASTM A890 Grade 5A or another approved super duplex grade. These material designations should not be treated as interchangeable without confirming the component form and project specification.
Key Design Features
- Super duplex pressure-containing construction.
- Wedge-gate straight-through flow path.
- Flanged or butt-weld connection options.
- Manual, gear or actuated operation.
- Project-specific trim and bolting.
