Cast Carbon Steel Valve
- Excellent flow performance: Small flow resistance and low erosion, suitable for high-pressure, high-temperature service.
- Versatile valve types: Can be supplied as ball, butterfly, plug, expanding, hydrogen and other special valve designs.
- Near-net-shape casting: Precision cast bodies minimize or eliminate subsequent machining operations, reducing cost and lead time.
- Robust construction: Simple structure, short face-to-face length, high thermostability and pressure resistance for demanding pipelines.
