Reverse Arched Fracture Disc (LF)

A composite assembly consisting of an arched slotted metal bursting disc, a sealing membrane, and a support bracket. The bursting pressure is controlled by the weakened structure formed by slots and holes on the dome surface of the disc. When the protected system exceeds its pressure limit, the bursting disc fractures along its weakest points to relieve pressure.
