Yes. Vajra Industrial Solutions supplies Diaphragm Valve (Sanitary / Aseptic), Sanitary Butterfly Valve, Sanitary Ball Valve, Needle Valve (Analytical / Sampling) for pharmaceutical & biotech (cleanroom / hygienic) applications in Kathmandu, Bagmati Province. Nepal's capital and procurement hub for major hydropower projects — Upper Tamakoshi (456 MW), Budhigandaki (1,200 MW), and Melamchi Water Supply — requiring AWWA-standard butterfly valves, pressure-reducing valves, and high-head stainless steel gate valves for mountain water systems. We offer export documentation and delivery to Kathmandu in 7–14 business days with full documentation and third-party inspection.

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.

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.

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.

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.
