QUALITY CONTROL

Quality Control for Sanitary Valves and Fittings

Quality control is applied throughout our production and inspection process. All products are visually inspected before delivery, and sampling inspections include tolerance inspection, surface roughness inspection, material inspection and valve pressure testing.

Material Inspection Tolerance Check Surface Roughness Pressure Testing
Material Verification XRF Test

Material, Tolerance and Surface Inspection

From raw material PMI verification (5% sampling) through in-process dimensional checks to final testing—including 100% ball valve leak testing, 5% roughness inspection, and pressure testing per API 598/ISO 5208/EN 12266-1 standards—Yuanzhou ensures full traceability. Every valve is batch-tracked with complete documentation: material certs, inspection reports, and pressure test records provided on request.

Valve Pressure Testing Equipment

Valve Pressure Testing

Using a 1.5″ 316L sanitary ball valve as an example: shell pressure tested at 8-10 bar for 5 minutes and seat seal tested at 8 bar for 3 minutes with purified water—zero leakage detected, meeting ISO 5208 standards, with all results documented in batch traceability files.

Surface Inspection

Roughness test Before Delivery

Internal bore surfaces tested at both ends: average Ra 0.467 μm, maximum Ra 0.58 μm—meeting Ra≤0.8 μm sanitary finish requirements. Results documented in batch traceability files.
