Explosion isolation devices are recommended to be installed on the pipelines of interconnected equipment and facilities with dust explosion hazards. When a dust explosion occurs, the explosion isolation valve, as a passive dust explosion isolation valve with CE and EX explosion-proof certifications, can effectively prevent explosion propagation, protect adjacent upstream equipment or workshops, and avoid secondary or multiple explosions.

When a dust explosion occurs in a dust collector or dust receiver, the high-temperature, high-pressure combustion products and unburned materials generated by the explosion can be discharged to a non-hazardous direction through the explosion venting device, so as to prevent the dust collector from being damaged.

When the equipment is installed indoors, the freely vented explosion flame and shock wave may cause secondary explosions and lead to greater losses. The flameless explosion venting device is designed to protect personnel and equipment from dust explosion damage. In case of a dust explosion, the explosion flame is extinguished by the flame arrester inside the device, and the pressure wave generated by the explosion is discharged safely.
