The explosion protection valve prevents the dust explosion from expanding beyond the place where it is fitted. The valve acts as a flame barrier at the same time. In the event of an explosion, the valve detects the event through the kinetic energy preceding the pressure wave, and closes of the affected area. It is primarily used in clean air situations.

The quick closing valve is part of an active explosion isolation system. In the event of ignition, it is activated by solenoid valves. Air flows out of a compressed air reservoir into the drive cylinder, closing the slide valve within milliseconds. Both the flames and the spread of pressure are effectively stopped. After having been triggered, the slide valve can be reactivated without needing a repair, and because of its non-destructive operation it can be validated at any time.

This active system is used to decouple the emerging flame front. The barrier is particularly useful in reduced-pressure equipment, in combination with explosion pressure relief or explosion suppression systems. In the event of a hazardous event, gas generators activate the extinguishing agent bottle. The extinguishing powder is forced with great speed into the pipeline that is to be decoupled, reliably extinguishing the oncoming flame. The fast activation – or opening – of the extinguishing agent bottle is achieved through a specially developed, reusable leaf valve. After having been triggered, this valve can quickly be replaced, allowing the whole system to be reactivated again in a very short time. Your plant therefore does not have to stay out of operation for long.
