Yuanzhou supplies high-purity stainless steel valves, ASME BPE fittings, electropolished tubing and sanitary components for pharmaceutical manufacturing, bioprocessing, vaccine production and biopharmaceutical systems. Our products meet ASME BPE, FDA, cGMP and cleanroom requirements for sterile processing environments.
Pharmaceutical and biotech processing requires components that meet strict material purity, surface finish and validation documentation standards. Yuanzhou manufactures ASME BPE fittings, electropolished valves and tubing with Ra ≤ 0.4μm surface finish, full traceability and material certificates compliant with FDA 21 CFR Part 11 and EU GMP Annex 1 requirements.
We work with pharmaceutical equipment manufacturers, biotech facility engineers and validation teams to supply components for API production, bioprocessing systems, sterile filling lines, WFI distribution systems and high-purity chemical handling. All products are manufactured under controlled conditions with documented batch records and inspection reports.
