VIGIFLAP – Explosion Isolation Valve

VIGIFLAP Explosion Isolation Valve is a non-return valve designed to prevent overpressure or flame caused by a downstream explosion to propagate in the piping system.

The valve is held open by a lever arm. It can be used both at the entrance and at the exit of the filter.
This allows to isolate the filter of an explosion or an overpressure.

In case of explosion, the valve closes and remains locked preventing the passage of the flame.

The unlocking of the flap is done manually.
