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.

• Low turbulence under normal circumstances, thereby saving energy
• Automatic closure in the event of an explosion
• Used for dusts with dust explosion classes St 1 and St 2 Horizontal fitting (a special version can, if required, be fitted vertically)
• Fitted according to the direction of the explosion
