Hygienic Process Assurance: COVNA Food-Grade Valve Systems
In food and beverage manufacturing where a single CFU (colony-forming unit) can trigger product recalls, COVNA’s hygienic valves deliver uncompromising contamination control. Engineered to exceed FDA 21 CFR Part 177 and EC1935/2004 standards, our solutions prevent cross-contamination risks across thermal processing, CIP cycles, and aseptic filling operations.
Triple Barrier Contamination Defense
1. Material Integrity
Direct Contact Surfaces: Electropolished 316L stainless steel (Ra ≤0.4μm) with 2B/BA finish
Sealing Systems: FDA-compliant EPDM/FKM with ECOLAB® antimicrobial certification
Drainage Design: 100% self-draining capability (3° minimum slope per EHEDG guidelines)
2. Microbial Control
Steam-in-place (SIP) ready: Withstands 140°C/30min sterilization cycles
Dead-leg elimination: Optimized flow geometry (L/D ratio <2)
Biofilm prevention: Mirror-polished surfaces (Ra <0.8 μm)
3. Process Reliability
CIP-optimized valve bodies: 4D radius bends for 2.5m/s scouring flow
Particulate control: Dual-seat design with 0.01mm particle retention
All-welded construction: Eliminate crevices in high-risk zones (Zone 1/Zone 2)
