Product Overview
The KOZO Alloy 20 Gate Valve is intended for selected acid and corrosive chemical services where Alloy 20 materials are specified. The full-bore wedge-gate arrangement is used for on/off isolation rather than throttling.
Why Alloy 20?
Alloy 20 is a nickel-iron-chromium alloy system containing molybdenum and copper. It is commonly considered for certain sulfuric-acid and chemical-processing duties. Cast components may use ASTM A351 CN7M while wrought components use the applicable Alloy 20 grade.
Key Design Features
- Alloy 20 / CN7M material options.
- Wedge-gate straight-through isolation.
- Flanged or welded connection options.
- Handwheel or gear operation.
- Project-specific trim and packing materials.
