Critical Valve 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)
EHEDG certification or design assessment for food and pharma contact
Full material traceability — EN 10204 3.1 certificates for SS components

What certifications are required for pharmaceutical & biotech (cleanroom / hygienic) valves in Kathmandu?
For pharmaceutical & biotech (cleanroom / hygienic) in Kathmandu, the applicable standards are: USP Class VI, EHEDG, FDA 21 CFR, 3-A Sanitary Standards, ISO 9001:2015, EN ISO 1672-2 (Hygienic design), GMP (WHO / EU). All valves are supplied with full documentation including material test reports (EN 10204 3.1/3.2), pressure test certificates, and dimensional inspection reports. Third-party inspection (TPI) by EIL, Bureau Veritas, Lloyd's Register, or the client's nominated inspector can be arranged.
What is the delivery time for pharmaceutical & biotech (cleanroom / hygienic) valves to Kathmandu?
Standard stock sizes: export documentation and delivery to Kathmandu in 7–14 business days. Custom sizes and special materials (Duplex, Hastelloy, P91): 4–8 weeks manufacturing lead time. 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 a zero dead-leg valve in pharmaceutical piping?
A zero dead-leg valve is designed so that when the valve is installed in a pipeline, there is no stagnant section (dead leg) of fluid trapped in the valve body. Dead legs are a primary source of microbial contamination and biofilm formation in pharmaceutical water systems. Diaphragm valves with a 'T' or 'flush-bottom' design, and sanitary ball valves with full-bore ports, minimise dead legs.
What surface finish is required for pharmaceutical valves?
Pharmaceutical standards (FDA, ISPE, EHEDG) typically require internal product-contact surface finish Ra ≤0.8μm for most applications, and Ra ≤0.4μm or better for WFI and sterile applications. Surface finish is measured by profilometry. Electropolishing (EP) improves corrosion resistance beyond mechanical polishing and is increasingly specified for WFI loops and sterile manufacturing. Vajra can supply valves with specified surface finish certificates.
