Q-Flap non-return explosion valves can be used to isolate explosions effectively in virtually all areas of industry. Q-Flap is suitable for use in aspiration filter suction lines and horizontal pipes.
When an explosion occurs, the flap is closed by the pressure front that spreads through the duct. The explosion can spread no further through the pipe. Staff working at capturing points or system components beyond the valve flap are protected against the effects of the explosion. The flap damping element and the locking unit prevent the flap from opening again shortly after the explosion due to the low pressure created in its aftermath.
