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.
Types
Round Conventional Slotted Domed Rupture Disk (LF)
Rectangular Conventional Slotted Domed Rupture Disk (LFF)

◆ Designed for gas, liquid, dust service.
◆ Maximum operating pressure up to 80% of the minimum burst pressure.
◆ Few fragments on burst.
◆ Withstand vacuum and backpressure with vacuum support.
◆ Complex structure.
◆ Suitable for low burst pressure conditions.
◆ Poor fatigue resistance in pressure cycling conditions.
