1. Process flow

The production process of the ball valve is systematically integrated into ball valve automatic production line and ball valve conveyor production line, with material and process adaptations for brass ball valve production line.

• Material preparation:  automatic production line supports stainless steel, carbon steel, and titanium alloy for general valves, while production line specializes in lead-free brass (corrosion resistance ≥95%) for sanitary applications. Material selection directly impacts the ball valve’s durability in high-temperature/high-pressure scenarios.

• Sphere processing: In ball valve conveyor production line, hot forging (temperature control ±10℃) and spinning form spherical blanks with roundness ≤0.005mm.  production line uses cold extrusion for brass spheres, reducing machining time by 30% while ensuring hole alignment (positioning error ≤0.02mm) for valve stems.

• Seat machining: CNC grinders in ball valve automatic production line shape seats to match spheres with surface roughness Ra≤0.4μm. For production line, nickel-plated seats (thickness 10-15μm) enhance sealing against brass spheres.

• Valve body machining: Ball valve conveyor production line machines bodies into spherical/elongated shapes with five-axis centers (tolerance ±0.01mm), while brass ball valve production line adds deburring stations to eliminate burrs in brass castings (残留毛刺高度≤0.05mm).

• Assembling: Robotic arms in ball valve automatic production line install O-rings (compression rate 35%-45%) and stems with torque control (5-10N·m). production line uses anti-twist fixtures to protect soft brass threads during assembly.

• Testing: All the ball valve units from ball valve automatic production line undergo hydraulic tests (pressure 1.5×rated, hold 5min) and gas tightness checks (leakage ≤1×10⁻⁹ Pa·m³/s). Brass ball valve production line adds salt spray testing (96 hours) for corrosion compliance.

2. Technical features

High degree of automation

Ball valve automatic production line achieves 95% automation, with ball valve conveyor production line’s AGV trolleys (navigation error ≤15mm) transporting workpieces between stations. Brass ball valve production line integrates dedicated brass-polishing robots (speed 2000rpm), reducing manual intervention by 70%.

High-precision processing

Vision sensors in ball valve automatic production line inspect sphere diameters (accuracy ±0.002mm), while brass ball valve production line uses eddy current testing to detect micro-cracks in brass bodies (depth ≥0.1mm). The ball valve’s stem-to-ball clearance is controlled within 0.03-0.05mm via servo presses.

Intelligent inspection

Real-time data from ball valve conveyor production line’s pressure sensors (accuracy ±0.5%) and brass ball valve production line’s mass spectrometers (gas purity ≥99.99%) ensure the ball valve meets API 6D standards. Defect alarms trigger within 3 seconds of detection.

Flexible & eco-friendly

Modular tooling in ball valve automatic production line enables quick switchovers between 1/4"–6" valves (<20min), while brass ball valve production line adapts to leaded/lead-free brass via material recognition systems. Energy recovery systems in both lines cut power consumption by 18%.
