Engineered for reliability in the most demanding pipeline environments, Chengxin Valve's Industrial Grade ANSI Cast Steel Check Valve delivers uncompromising performance for oil and gas applications. This heavy-duty valve prevents costly backflow incidents through its robust cast steel construction and precision engineering. With over three decades of manufacturing expertise since 1993, we ensure each valve meets stringent international standards while optimizing operational safety and efficiency.
The valve's zero-leakage design maintains pipeline integrity even under extreme pressure fluctuations, significantly reducing maintenance downtime across upstream, midstream, and downstream operations.
- Body Material: ASTM A216 WCB carbon steel with superior corrosion resistance
- Disc Design: Swing-type with full-bore flow for minimal pressure drop
- Sealing System: Metal-to-metal seat ensures bubble-tight shutoff at 600psi
- Surface Treatment: Electroless nickel plating optional for sour service environments
- Installation Flexibility: Horizontal or vertical mounting without performance compromise
| Size (inch) | Pressure Class | Flow Coefficient (Cv) | Weight Range (lbs) |
|---|---|---|---|
| 2" - 8" | 150 - 300 | 120 - 2,800 | 25 - 180 |
| 10" - 16" | 300 - 600 | 3,100 - 8,500 | 210 - 950 |
| 18" - 24" | 600 | 9,200 - 15,000 | 1,100 - 2,400 |
Operational advantages include reduced water hammer effect through controlled closing speed and field-replaceable internals that extend service life beyond standard industry expectations. The streamlined flow path design achieves 98% flow efficiency, cutting energy consumption in high-volume transfer systems.
