All castings undergo rigorous non-destructive testing (NDT) such as X-ray or ultrasonic inspection.
- 3. CNC Machining: Precision is paramount. Advanced Computer Numerical Control (CNC) machines meticulously machine the valve body, bore, stem hole, and seat pockets to tight tolerances (typically ±0.05 mm or better). This ensures perfect fitment of internal components, smooth operation, and superior sealing capabilities. Automated gauging systems verify dimensional accuracy, and surface roughness is controlled to prevent wear and corrosion.
- 4. Ball and Stem Fabrication: The ball, crucial for flow control, is machined from a solid bar or forging, often mirror-polished (Ra
- 5. Seat and Seal Component Preparation: Valve seats (e.g., Virgin PTFE, RPTFE (reinforced PTFE), PEEK, Delrin, or metal seats) and stem seals (e.g., O-rings, graphite packing) are selected based on anticipated temperature range, chemical compatibility, pressure requirements, and fugitive emission standards. These components are molded or machined to exact specifications and undergo material verification (e.g., PMI - Positive Material Identification for alloys).
- 6. Assembly: All components are carefully assembled in a clean environment, adhering to strict torque specifications for fasteners and ensuring proper alignment of the ball and stem. Specialized tools and fixtures are used to prevent damage to sealing surfaces.
-
7. Testing and Quality Assurance: Every valve undergoes rigorous testing to comply with international standards such as ISO 5208 (pressure testing), API 598 (valve inspection and testing), and ANSI/ASME B16.34 (valves—flanged, threaded, and welding end).
- Hydrostatic Shell Test: Verifies the integrity of the valve body and body joint (if any) under 1.5 times the rated working pressure.
- Seat Leakage Test: Ensures bubble-tight shut-off in both directions at 110% of rated working pressure (liquid) and low pressure (gas), typically to API 598 or ISO 5208 Rate A standards.
- Fugitive Emissions Testing (ISO 15848-1 / TA-Luft): For critical applications handling hazardous or volatile media, specialized testing verifies minimal stem leakage over a specified number of cycles.
- Operational Torque Test: Measures the force required to operate the valve, ensuring it falls within design specifications for manual or automated actuation.
- 8. Surface Treatment & Packaging: Final surface treatments (e.g., painting, passivation, electro-polishing) are applied for enhanced corrosion resistance and aesthetic finish. Valves are then carefully packaged, often with protective caps and desiccants, to prevent damage during transit and storage.
