Heavy-duty explosion-proof solenoid valve with intrinsically safe coil design, featuring redundant sealing and spark-resistant construction. The aluminum alloy body undergoes special surface treatment for hazardous environments. Requires 25μm filtered dry air and periodic lubrication (every 3M cycles). Includes surge protection circuit for voltage stability.
- Petrochemical plant gas control systems
- Coal mine ventilation equipment
- Grain processing dust explosion zones
- Paint spray booth safety shutoffs
- Oil refinery pneumatic actuators
- Aviation fuel handling systems
Installation note:
Must be grounded via M6 terminal. Maintain minimum 200mm clearance from ignition sources.
Use copper alloy tools within Ex zones. Perform monthly diaphragm inspection in corrosive environments.
