The WCB cast steel body provides higher structural toughness and plasticity than DI bodies, ideal for high-stress environments.
Opens and closes automatically based on medium flow, eliminating the need for external power sources.
Fully compliant with API, ASME, DIN, and JIS standards for seamless international integration.
Optimized for fluid systems with extreme high or low temperatures where standard valves fail.
Precision-engineered circular discs ensure a tight seal to completely block medium backflow.
Standard flanged connections allow for rapid installation and easy maintenance across various pipe networks.
Rigorous pressure testing and material certification for every cast steel valve unit.
Advanced CNC machining for flange surfaces to ensure leak-proof connections.
Optimized supply chain management for fast delivery of standard size check valves.
Expert guidance on valve sizing and material selection for specific industrial media.
Real-time tracking of WCB and DI valve stocks to meet urgent project deadlines.
Ability to adapt flange types and pressure ratings to meet unique site requirements.
| Feature | WCB Steel Body | DI Body (Ductile Iron) |
|---|---|---|
| Pressure Limit | High (Up to Class 900) | Moderate (Up to Class 150) |
| Temp Resilience | Excellent High/Low Temp | Limited Temperature Range |
| Structural Toughness | Superior Plasticity | Brittle Comparison |
| Lifespan in Corrosive Media | Extended Duration | Standard Duration |
| Maintenance ROI | Lower Long-term Cost | Frequent Replacement Cost |
WCB (Cast Steel) bodies offer significantly higher strength, toughness, and plasticity compared to DI (Ductile Iron), making them suitable for higher pressures and more extreme temperature environments.
It uses a circular disc that opens with the force of the forward flow and closes automatically under its own weight and the pressure of the returning medium.
The WCB body check valves are manufactured according to API 6D, ASME B16.34, DIN 3202, BS 1868, and JIS B2071 standards.
They are widely used in oil and gas, chemical processing, power generation, and water treatment where preventing reverse flow is critical for safety.
Available options include Class 150, 300, 600, and 900, as well as PN10, 16, 25, 40, 63 and JIS 5K, 10K, 16K.
Yes, due to the WCB cast steel construction, these valves are designed to handle the high temperature and pressure demands often associated with steam systems.
