Explosion-proof solenoid valves can be used in hazardous areas, but only when designed with proper explosion-proof (Ex-proof) certifications.

Key Requirements for Safe Operation

Explosion-Proof Certifications

• Must comply with ATEX, IECEx, UL, or CSA standards (e.g., ATEX II 2G Ex db for gas hazards)
• Solenoid valves should have intrinsically safe (IS) coils to prevent sparking

Hazardous Area Classification

• Suitable for Zone 1/Zone 2 (gas) or Zone 21/22 (dust) per IEC/ATEX standards
• Class I, Div 1/2 (North America) for flammable gases/vapors

Construction & Materials

• Sealed, corrosion-resistant enclosures (e.g., stainless steel or coated aluminum)
• Spark-free operation with non-arcing contacts
