Precision and quality are non-negotiable for ball valve balls used in industrial critical infrastructure. Our QC process：

CNC Machining: Forging → turning → heat treatment → precision grinding (Ra ≤0.02μm)
Dimensional Inspection: CMM (coordinate measuring machine), ±0.001mm tolerance
Material Verification: PMI (positive material identification), hardness test (HRC/Vickers)
Pressure & Leakage Test: 100% hydrostatic pneumatic test, API 598 VI 级
Certification: API 6D, ISO 9001, CE, NACE MR0175

We guarantee zero defect delivery for all high-precision ball valve balls.
