CHAODA VALVES

Cast Carbon and Stainless Steel Gate, Globe, and Check Chaoda Valves

CAST WITH PRECISION SINCE 1984

Foundry-Grade Performance, Engineered to Last

We carry a full range of Chaoda cast carbon and stainless steel gate, globe, and check valves designed to meet the demands of industrial markets. Since 1984, the Chaoda Group has built a strong reputation for producing high‑quality valves at competitive prices. Their state‑of‑the‑art foundry allows them to cast all their valves in‑house, including those made from exotic alloys, ensuring precise quality and consistent performance every time.

In-House Casting, Every Time

Chaoda's state-of-the-art foundry casts all valves in-house, including exotic alloys, ensuring precise quality control and consistent performance across every valve they produce.

Straight-Through Flow Performance

Built to API standards, Chaoda OS&Y gate valves deliver bi-directional, straight-through flow that minimizes pressure drop and flow loss in applications where tight shut-off is critical.

Precision-Engineered Sealing

Globe valves feature a backseat design for leak-path protection, welded seat rings in carbon steel bodies, and an integral one-piece forged stem built for durability and long-term sealing reliability.

Dependable Backflow Prevention

From swing check valves with anti-rotation discs and internally retained hinge pins, to dual plate wafer check valves with Inconel X-750 springs, Chaoda delivers trusted backflow prevention for critical flow-control applications.

Designed to Perform

Chaoda Gate Valves

Chaoda OS&Y gate valves are built to industry standards, thus providing straight-through, bi-directional flow that minimizes flow loss and pressure drop. These valves excel especially in applications where smooth flow and tight shut-off are critical, making them ideal for industries that require reliability and efficiency.

Precision Sealing

Chaoda Globe Valves

Chaoda cast globe valves stand out for their durability and precision. Each design includes a backseat feature, thus allowing for effective sealing if packing leakage occurs. Moreover, in our cast carbon steel globe valves, the seat ring is welded securely into the body, ensuring long-lasting performance. Meanwhile, our cast stainless steel globe valves feature an integral seat as a standard design. All Chaoda globe valves utilize an integral, one-piece forged stem for added strength and reliability.

Reliable Backflow Prevention

Chaoda Swing Check Valves

For dependable backflow prevention, Chaoda swing check valves are an ideal choice. They come standard with internally retained hinge pins, removing potential leak paths and making maintenance easier. An anti-rotation feature prevents the disc from rotating more than 360°, reducing wear and extending service life. In addition, these cast carbon steel swing check valves feature a seal-welded seat ring, while cast stainless steel swing check valves have integral seats as a standard design. Together, these features make our swing check valves a trusted solution for critical flow-control applications.

Lightweight & Responsive

Chaoda Dual Plate Wafer Check Valves

Chaoda dual plate wafer check valves offer a low-cost option to assist in preventing backflow. These valves are lighter, more responsive, and better at handling pulsating flow than swing check valves. They are designed to internally prevent typical external stem leakage, and their construction removes all potential leak paths from the valve body. Additionally, these dual plate wafer check valves come standard with Inconel X-750 torsional springs, while other spring materials can be provided upon request.
