With stable and traceable process routes and a rigorous metrology system, we ensure each valve operates reliably under high pressure, high temperature, and corrosive conditions. Full-process quality control covers materials, machining, assembly, and testing.
Complex flow channels and multi-face forming in a single setup reduce cumulative errors and improve contour and positional accuracy.
Precision machining of rotating parts such as valve bodies, covers, and stems, ensuring control over concentricity, runout, and surface roughness.
Program-controlled torque and displacement monitoring, traceable consumable batches, and reduced leakage risk caused by human variability.
Measures complex geometries and geometric tolerances, establishing stable reference systems and probing strategies.
Hydrostatic and pneumatic testing for each unit, with automatic recording and retention of leakage rates and pressure-holding curves.
Verifies incoming material composition and traces heat numbers to prevent substitution risks.
Acceptance of materials and outsourced parts: verification of composition, dimensions, surface condition, certificates, and labeling.
First-piece, patrol, and final inspections; step-by-step verification of key dimensions and error-proofing points.
Sampling of key dimensions and trend monitoring; out-of-tolerance alerts and rapid response handling.
Verification of appearance, dimensions, and functionality; confirmation of status and parameters before testing.
Verification against order and standards: nameplate, documentation, packaging, test records, and certificates of conformity.
