Explosion duct valve

The explosion duct valve is used in order to prevent that an explosion in the plant will be channelled back to the production premises and machines. The explosion duct valve is mounted on the duct section between the plant and the dust source. The explosion duct valve stops explosions that occur in both flow directions of the normal flow. This means that the explosion duct valve can be mounted on both the inlet side and the outlet side on the dust separator. The dust separator covers filters, silos and industrial exhausters which are already protected with explosion relief or explosion suppression system.

It is delivered with position switch. The explosion duct valve is painted in RAL 3020.
