Butterfly Valves for Pharmaceutical & Biotech (Cleanroom / Hygienic)
SS 316L diaphragm, sanitary butterfly, and aseptic ball valves for pharmaceutical, biotech, and cleanroom process lines - USP Class VI, EHEDG, FDA compliant.
Which butterfly valves are used for pharmaceutical & biotech (cleanroom / hygienic)?
Pharmaceutical manufacturing, API production, and biotech fermentation require hygienic valves that prevent microbial harbourage, withstand CIP (Clean-in-Place) and SIP (Steam-in-Place) cycles, and comply with FDA 21 CFR, USP Class VI, and EHEDG design criteria. Material, surface finish (Ra ≤0.8μm), and zero-dead-leg design are critical for contamination control.
Sanitary Butterfly Valve
Process isolation in CIP-compatible design for larger bore lines (DN50–DN200)
Critical Requirements
- SS 316L (minimum) - low carbon content prevents sensitisation and corrosion
- Internal surface finish Ra ≤0.8μm (ID) for product-contact surfaces - electropolished preferred
- Zero dead-leg design - prevents microbial growth in stagnant sections
- CIP compatibility - withstand NaOH (1–2%), HNO₃ (1%), and steam at 121–134°C
- SIP (Steam-in-Place) capability - steam sterilisable at 134°C / 3 bar
- USP Class VI / FDA material compliance for elastomers (EPDM, silicone, PTFE)
Service Challenges
- WFI (Water For Injection) - highly corrosive to carbon steel; requires SS 316L minimum
- Strong CIP chemicals (NaOH, HNO₃, PAA) - chemical resistance of elastomers critical
- Steam (SIP) - thermal cycling requires compatible materials and design
- Bioburden control - dead legs in valves are primary source of microbial contamination
- Oxygen-sensitive products - zero-leakage to atmosphere required
