Conventional Domed Slotted Lined Bursting Disc

CONVENTIONAL SLOTTED DOMED RUPTURE DISK (LF TYPE)

Conventional Slotted Domed Rupture Disk consists 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.
