A dedicated check valve solution for harsh operating conditions—featuring large diameter, low pressure drop, and high reliability. Through an external swash plate and gravity-assisted structure, it achieves precise and smooth control of medium backflow, making it particularly suitable for low-pressure, high-flow pipeline systems or those requiring slow closing to prevent impact.

| Feature | Wafer-Type Tilting Disc Check Valve (with heavy punch) | Regular Swing/Double Disc Check Valve |
| Closing Force | Primarily gravity-assisted, adjustable slow-closing | Relies on medium backflow impact |
| Water Hammer Control | Active energy dissipation, highly effective | Passive closing, prone to water hammer |
| Flow Resistance Coefficient | Very low (close to straight pipe) | Relatively high |
| Maintenance Convenience | External components allow inspection without disassembly | Requires valve body disassembly |
| Condition Adaptability | Suitable for low pressure, high flow, and media containing impurities | Suitable for clean media and stable conditions |
