Heavy-duty explosion-proof solenoid valve engineered for hazardous environments requiring ATEX/IECEx compliance. Features brass main body with stainless steel core components and anti-corrosion coating. The dual-chamber explosion-proof design prevents internal spark propagation, with a flame arrestor path ≤40mm. Requires 5μm filtered compressed air or inert gases.
- Petroleum refinery gas control systems
- Coal mine methane ventilation controls
- Paint spray booth pneumatic circuits
- Grain silo dust explosion prevention systems
- Chemical processing plant valve actuators
Critical installation requirements:
Maintain 300mm clearance from potential ignition sources. Use copper alloy tools within explosive atmospheres.
Grounding resistance must be ≤10Ω. Do NOT operate when ambient exceeds temperature class T4 (135℃ surface temp).
