Explosion Isolation Valve

An explosion isolation damper is a non-return valve designed to prevent overpressure or flame caused by a downstream explosion (dust collectors, filters, cyclones…) 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 isolating the filter from an explosion or an overpressure.

 In case of an explosion, the valve closes and remains locked preventing the progress of the flame. The unlocking of the flap is done manually.
