The VigiFLAP can be used as both an upstream and downstream protection device when used on each side of the protected vessel. To accomplish this, the VigiFLAP uses a unique locking mechanism that allows the valve to be held open in a working position, with the ability to quickly close during an event. This locking mechanism also reduces the pressures drop experienced in many similar isolation type devices.
In the event of an explosion or deflagration, the valve will close, lock and prevent the passage of flame. Unlocking of the flap once it has been closed, must be completed manually at the locking mechanism.
