SS 316 Rectangular Conventional Slotted Domed Rupture Disk (LFF)
Conventional Slotted Domed Rupture Diskconsists of a slotted metal top section and a seal membrane. Burst pressure is controlled by the slotted and perforated top section. When excessive pressure occurs on the protected system, the disk bursts along the pre-slotted lines to provide a full relief opening.
