Critical Valve Requirements

SS 316L minimum for all product-contact surfaces — low carbon content prevents sensitisation
Internal surface finish Ra ≤0.8μm (ID) for product-contact surfaces, Ra ≤0.4μm for sterile and WFI applications
3-A Sanitary Standards or EHEDG certification — proof of cleanability and hygienic design
CIP compatibility: valves must withstand NaOH (0.5–2%), HNO₃ (0.5–1.5%), and peracetic acid (PAA, 0.1–0.3%) at 70–85°C
SIP capability: selected valves must withstand steam at 121–134°C for sterilisation cycles
Zero dead-leg design: dead-leg length ≤2 × internal pipe diameter per ISPE Baseline Guide
USP Class VI / FDA 21 CFR compliant elastomers: EPDM, silicone, or PTFE for product-contact seals
Drainability: valve and piping design must be fully self-draining to prevent product pooling

What certifications are required for hygienic food & beverage processing valves in Ulsan?
For hygienic food & beverage processing in Ulsan, the applicable standards are: 3-A Sanitary Standards (USA), EHEDG (European Hygienic Engineering & Design Group), FDA 21 CFR 177 (Plastics), FDA 21 CFR 178 (Adjuvants), USP Class VI, FSSAI (Food Safety and Standards Authority of India), EN 1672-2 (Hygiene requirements for food machinery), ISO 9001:2015.

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What is the difference between 3-A Sanitary Standards and EHEDG for valve selection?
Both 3-A and EHEDG define hygienic design requirements but originate from different regions and have different testing approaches. 3-A Sanitary Standards (USA) require physical cleanability testing (cleaning test with validation) and cover specific equipment types with detailed design criteria. EHEDG (European Hygienic Engineering and Design Group) certifies equipment through a combination of design review and cleanability testing. For equipment sold in the USA, 3-A is typically required; for EU and most international markets, EHEDG is the preferred standard. Both are widely accepted globally, and leading valve manufacturers often hold both certifications.
What surface finish is required for food-grade stainless steel valves?
For most food and beverage applications, the internal product-contact surface finish should be Ra ≤0.8μm (equivalent to 32 micro-inch Ra in US units). For sterile and aseptic applications (UHT, aseptic filling), Ra ≤0.4μm is required. Electropolishing (EP) is preferred for sterile applications as it removes micro-surface defects and reduces surface area for microbial attachment. Mechanical polish to Ra 0.8μm is acceptable for most non-sterile dairy and beverage service. Surface finish certificates (profilometry reports) should be provided with valve documentation.
