Product Overview
The KOZO 904L Stainless Steel Gate Valve is designed for corrosive chemical and acid-handling systems where UNS N08904 / 904L construction is specified. The wedge-gate design provides straight-through on/off isolation with low flow resistance when fully open.
Why 904L?
904L is a high-alloy austenitic stainless steel containing elevated nickel, chromium and molybdenum with copper additions. It is used in selected sulfuric-acid and chloride-containing environments where conventional 316L may not provide sufficient corrosion resistance.
Key Design Features
- 904L / UNS N08904 pressure-containing construction.
- Wedge-gate straight-through flow path.
- Flanged or butt-weld end options.
- hệ điều hành&Y stem arrangement depending on design.
- Handwheel, gear or project-specific actuation.
