Chemical & Pharma Valves
Industrial Valves for Chemical & Pharma
Corrosion-Resistant & Sanitary Valves for Chemical and Pharmaceutical Processes
Chemical and pharmaceutical plants handle aggressive media - acids, alkalis, solvents, halogens - that attack conventional valve materials. They also require ultra-high purity, crevice-free construction for active pharmaceutical ingredient (API) manufacturing. Vajra supplies corrosion-resistant and high-purity valve solutions in SS316L, Hastelloy C-276, PVDF, and rubber-lined constructions.
What valves does the Chemical & Pharma industry use?
Chemical and pharmaceutical plants handle aggressive media - acids, alkalis, solvents, halogens - that attack conventional valve materials.
Key Chemical & Pharma Applications
We supply application-specific valve solutions for each segment of the chemical & pharma industry.
Bulk Chemical Processing
Corrosion-resistant ball valves and butterfly valves for handling acids (HCl, H2SO4, HNO3), alkalis, solvents, and organic chemicals. PVDF-lined, PTFE-lined, or rubber-lined bodies for aggressive media. SS316 and duplex SS for halide-containing streams.
Pharmaceutical API Manufacturing
Sanitary ball valves and diaphragm valves in SS316L for API and intermediates. Electro-polished internal surfaces (Ra ≤ 0.4μm) for cleanability and minimal product retention. USP Class VI elastomers for product contact parts.
Fertiliser & Agrochemical Plants
Gate valves and globe valves for ammonia, urea, and phosphoric acid service. Alloy steel and SS316 for ammonia synthesis loop service. Hastelloy C-276 for phosphoric acid and chloride-containing fertiliser streams.
Chlor-Alkali & PVC Plants
Rubber-lined butterfly valves and PVDF-lined ball valves for chlorine, sodium hydroxide, and chloride service. Titanium and Hastelloy C-276 for wet chlorine gas service. Strict leak-tightness required for toxic gas containment.
Solvent Recovery & Fine Chemicals
SS316L ball valves with Hastelloy or Monel stem and trim for solvent-handling. Fire-safe designs for flammable solvent service. ATEX-rated actuators for explosion-hazard areas (Zone 1 and Zone 2).
