1. Core Product Features

Full process automation coverage

Stainless steel valve assembly line, brass valve assembly line, and large calibre valve assembly line all feature full-process automation, with specialized modules for material adaptation:

• Parts processing: CNC lathes and five-axis centers in stainless steel valve assembly line handle duplex stainless steel (hardness HRC 30-35), while brass valve assembly line uses dedicated brass-cutting tools (tool life ≥1,000 hours) for lead-free brass components. calibre valve assembly line employs heavy-duty machining centers (load capacity ≥5 tons) for DN1200+ valve bodies, ensuring dimensional accuracy ±0.02mm.

• Intelligent assembly: Robots in brass valve assembly line use anti-twist grippers (force control ±0.5N) to install soft brass seals, while large calibre valve assembly line integrates hydraulic presses (pressure 50-100 tons) for gasket compression. All lines achieve ±3% torque accuracy in bolt tightening.

• Precision testing: valve assembly line adds ultrasonic testing for weld integrity (defect detection ≥0.2mm), while brass valve assembly line includes 96-hour salt spray tests (corrosion rate ≤0.01mm/year). calibre valve assembly line features dual-pressure test benches (up to 40MPa) for high-pressure validation.

Flexible production capacity

• Multi-species compatibility: Quick-change tooling in brass valve assembly line switches between decorative brass valves and industrial brass ball valves in ≤15 minutes. Large calibre valve assembly line uses modular conveyors to adapt to DN500-DN2000 pipelines, while valve assembly line supports 304/316L material changes via barcode scanning.

• Customized adaptation: For corrosion-resistant needs, stainless steel valve assembly line offers electropolishing (surface roughness Ra≤0.2μm), while brass valve assembly line provides nickel-plated brass options (plating thickness 8-12μm). Large calibre valve assembly line customizes sealing structures for low-temperature (-196℃) LNG applications.

Data-driven quality management

• Full-process traceability: QR codes in stainless steel valve assembly line track heat treatment parameters (temperature ±5℃), while brass valve assembly line records brass alloy composition (Cu≥58%, Pb≤0.2%). Large calibre valve assembly line logs hydrostatic test data (pressure hold time ≥30 minutes) for ASME B16.34 compliance.

• Real-time monitoring: MES systems in large calibre valve assembly line detect abnormal vibration (threshold ≥5mm/s) during testing, while brass valve assembly line uses conductivity sensors to verify plating adhesion (≥5B rating). All lines maintain ≤0.5% defect rates.
