Critical Valve Requirements

Wet chlorine gas - PVDF or PTFE-lined body, titanium disc; absolutely no iron, nickel-chromium alloys (attacked by wet Cl₂); no copper; FKM or PTFE packing only
Dry chlorine gas (< 20 ppm moisture) - carbon steel is surprisingly acceptable for dry Cl₂; however most plants keep SS316 or titanium as standard
Hydrochloric acid (all concentrations) - Hastelloy C-276 or titanium; SS316 only for dilute (<5%) cold HCl; NEVER use carbon steel
Caustic soda (NaOH) - SS316L acceptable for <70% NaOH; avoid aluminium (catastrophic SCC in NaOH); EPDM diaphragm valves preferred for slurry-free NaOH
Hydrogen gas from electrolysis - ATEX Zone 1; all electrical components on actuated valves must be Ex-certified
Brine (saturated NaCl) - titanium or rubber-lined butterfly; SS316 not reliable above 60°C in concentrated chloride

What certifications are required for chlor-alkali plants valves in Geismar?
For chlor-alkali plants in Geismar, the applicable standards are: ASME B16.34, ISO 9001:2015, API 609 (Butterfly), EN 12756 (Valve Stuffing Boxes), ATEX / IECEx (Chlorine Zone 1), Chlorine Institute Pamphlet 6.

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
Can I use SS316 valves for chlorine service in a chlor-alkali plant?
No - wet chlorine gas (Cl₂ with moisture) attacks austenitic stainless steel, including SS316. The chromium oxide passive layer that protects SS316 is destroyed by Cl₂ + HCl attack, causing rapid pitting and stress corrosion cracking. For wet chlorine, specify PVDF-lined butterfly valves (PN 10) or titanium ball valves. Dry chlorine (confirmed < 20 ppm moisture) can use carbon steel, but most plants maintain PVDF or titanium as a standard to eliminate moisture moisture monitoring from the maintenance programme.
What valve material handles both chlorine and caustic service?
Titanium Grade 2 is the rare material that resists both wet chlorine gas and dilute caustic soda - making it the preferred choice for brine and cell liquor service where both Cl₂ and NaOH are present. However, titanium is expensive and not suited for concentrated hot NaOH (>70%, above 80°C - risk of titanium stress corrosion cracking in very hot concentrated alkali). For pure caustic service, SS316L diaphragm valves are more economical.
