Critical Valve Requirements

Material compatibility matrix — each valve service must be individually checked against the specific chemical: SS316L is not suitable for hydrochloric acid or chloride-rich bleach above 60°C
IBR certification for all steam valves in Indian textile plants — steam to dyeing machines, calenders, and autoclave sterilisers above 3.5 kg/cm²
Hydrogen peroxide service — H₂O₂ is a strong oxidiser; PVDF or titanium body; PTFE or EPDM seats; no iron or copper contamination (catalyses H₂O₂ decomposition)
Sodium hypochlorite bleach — unstable above 40°C; SS316L and CPVC; no rubber in contact with NaOCl (attacks EPDM and NBR above 2% concentration)
Dye bath recirculation — large-bore DN100–DN300 butterfly valves required for high-volume dye vessel circulation; EPDM seat for pH 4–11 textile dyes
Wastewater treatment — valve materials for effluent must resist mixed chemicals; rubber-lined or SS316L butterfly valves

What certifications are required for textile & dyeing plants valves in Chittagong?
For textile & dyeing plants in Chittagong, the applicable standards are: ASME B16.34, IBR 1950 (Steam), API 598, ISO 9001:2015, FSSAI (where textile dyes are near food processing). All valves are supplied with full documentation including material test reports (EN 10204 3.1/3.2), pressure test certificates, and dimensional inspection reports.

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
Can SS316L valves handle all textile dyeing chemicals?
SS316L handles most textile chemicals: dye baths (pH 3–11), caustic soda (up to 70%), and mild oxidisers. However, SS316L is NOT suitable for: (1) hydrochloric acid above very dilute concentrations; (2) sodium hypochlorite above 2% at elevated temperature (above 40°C) — pitting and SCC; (3) hydrogen peroxide above 30% at elevated temperatures — H₂O₂ attacks SS316L above certain conditions. For these oxidising chemicals, specify PVDF, titanium, or CPVC valves. Always check a chemical compatibility chart against your specific dye bath pH, temperature, and concentration.
Are diaphragm or ball valves better for textile chemical dosing?
Both are used, and the choice depends on: (1) For clean chemical dosing lines (concentrated dye, softener, H₂O₂) — SS316L ball valves are preferred for their on/off reliability, compact size, and low maintenance. (2) For aggressive chemicals like bleach or peracetic acid where even SS316L may be marginal — PVDF or PP diaphragm valves eliminate metallic contact with the fluid and provide a safer solution. Diaphragm valves also provide easier visual inspection of the elastomeric diaphragm condition without disassembly.
