Chemical Processing Valves
Industrial Valves for Chemical Processing
Chemical-Resistant Valves for Every Process
Chemical plants process aggressive acids, solvents, alkalis, and toxic media requiring valves that resist corrosion, maintain tight shut-off, and meet fugitive emission standards. Vajra supplies SS316, Hastelloy C-276, Duplex, and PVDF-lined valves for fertiliser plants, chlor-alkali, acids, petrochemicals, and specialty chemical service.
