Customizable Valves for Complex Applications

Cast Steel Gate Valves

Unlike forging, casting uses the liquid form of metal to create valves. These metals are melted into a molten liquid and poured into various molds depending on the casting technology used. Chaoda has our own foundry equipped with state-of-the-art technology that allows us to pour all castings for our valves in-house including exotic alloys.

One of the biggest benefits of casting is that it can create valves with complex shapes, patterns, and sizes. Using a mold to manufacture these devices gives you more freedom to make different types valves with more intricate parts.


For when you get exactly what you need.

Chaoda OS&Y gate valves are specifically design to industry standards for straight thru, bi-directional flow which results in low flow loss and low pressure drop. They are designed for applications where excellent flow conditions and tight shut-off are necessary. Our gate valves proudly service the oil/gas refining, pulp and paper, power generation and chemical/petrochemical industries worldwide.

We offer both Cast API 600 and API 603 design Gate valve designs in a wide range of sizes, pressure classes and materials to fit even the most unique and rugged applications on the planet!
