Product Overview
The KOZO Alloy 20 Swing Check Valve is intended for selected acid and corrosive chemical systems where automatic non-return protection and Alloy 20 materials are required.
Why Alloy 20?
Alloy 20 is commonly considered for certain sulfuric-acid and chemical-processing duties. Cast pressure parts may use ASTM A351 CN7M, while other component forms use the applicable Alloy 20 wrought or forged grade.
Key Design Features
- Alloy 20 / CN7M material options.
- Swing-disc automatic non-return operation.
- Flanged or welded connection options.
- Project-specific hinge, seat and trim materials.
