4. Y Check Valves Manufacturing Process Explained
Flowchart: Y check valves manufacturing process (material traceability, key inspection nodes)
Key Process Insights: All y check valves components are rigorously NDT-inspected (magnetic particle, ultrasonic) and hydro-tested per ISO 5208/API 598, achieving leakage rates below 0.00001 ml/s. CNC finishing assures flatness < 0.0015 mm for metal-to-metal seats.
5. Technical Advantages of Y Type Check Valve Designs
- Superior Flow Performance: The Y pattern body minimizes flow turbulence and yields a high flow coefficient (Cv), surpassing swing or lift check valves in pressure drop efficiency.
- Anti-Water Hammer: Preloaded spring permits instantaneous valve closure, sharply reducing water hammer risk and pipeline stress.
- Enhanced Corrosion Resistance: All wetted parts can be duplex, super duplex, or alloy-coated to withstand aggressive media such as hydrocarbons, chlorides, or acids.
- Low Opening Pressure: Disc opens with a differential as low as 0.02 bar, critical for gravity flow and low-pressure pump discharge applications.
- Long Operation Lifetime: Life cycle test data (EN 12334) confirms >200,000 operations without performance decay. Actual on-field average: 18+ years with correct media.
- Maintenance Simplicity: Top entry bolting and seat access streamline periodic inspection or soft-part replacement, critical in harsh-duty settings.
