In regulated manufacturing, quality control is more than a checkpoint—it’s a commitment to consistent results, safe operations, and system reliability. At Duva Sanitary, we support these goals by sourcing components from partners who follow stringent production and inspection protocols aligned with 3A and BPE standards.
What Quality Control Means in Sanitary Systems
Sanitary system components must not only meet dimensional specs but also pass cleanliness, weld quality, and surface finish inspections. This ensures every product performs as expected and supports compliance with food safety or pharmaceutical manufacturing regulations.
Core Quality Practices
Dimensional and Visual Inspections
Each valve, fitting, and assembly must be verified for size, surface finish, and weld integrity. Common checks include surface roughness measurements (Ra values) and visual inspection under lighting to confirm cleanliness.
Material Certification and Traceability
Traceability is essential for GMP compliance. Certified manufacturers maintain documentation on material grades, heat lots, and production batches—allowing end-users to trace components back to source.
Non-Destructive Testing (NDT)
For critical applications, some manufacturers employ NDT methods like dye penetrant testing or radiographic imaging to detect internal flaws in welds or components without damaging them.
Application-Driven Requirements
Food Manufacturing
Quality assurance helps ensure that fittings and valves won’t corrode or fail during production or cleaning cycles. Components must consistently meet hygienic design standards to avoid recalls or downtime.
Pharma and Biotech
Here, verification extends to full documentation and often third-party audits. Surface finishes, weld profiles, and materials must meet exact standards to pass validation.
Why It Matters
- Avoid costly failures or contamination
- Ensure components meet cleanability and sterility expectations
- Comply with regulatory bodies like FDA, USDA, or EU MDR
- Support internal audits and customer quality standards
