Q-FLAP NX NOVEx

Cost effective passive isolation of dust collectors and cyclones

Applications

Q-Flap NX explosion isolation valve can be used to isolate explosions effectively in virtually all industries. The Q-Flap NX is suitable in filter lines with horizontal ductwork.

non return explosion valve Q-Flap NX
The Q-Flap NX ensures reliable explosion isolation to protect your plant and minimize the effects of an explosion.

Mechanism

Normal operation

During normal operation, the Q-Flap NX device remains opened due to magnets integrated inside the valve. The flap will close in the event of an explosion.

 

Explosion event

In the event of an explosion in any of the downstream equipment, the pressure wave will propagate towards the Q-Flap NX. This pressure wave will force the flap closed, preventing the explosion from propagating to other upstream processes. Employees working at capturing points or system components upstream of the Q-Flap NX are protected against the effects of the explosion. The flap locking mechanism prevents the flap from reopening shortly after the explosion due to the low pressure created in its aftermath.
