The Low Pressure LPS™ Reverse Buckling Disk and SRB-7RS Safety Head
LPS Rupture Disk (Bursting Disc) Features:
Solid Metal Design
Low burst pressure from 5 psig (0.35 barg)
Designed for gas, liquid or two phase service
Fail Safe: Damage Safety Ratio ≤1
Designed for non-fragmentation
Vacuum/back pressure resistant

The LPS Rupture Disk (Bursting Disc) was developed to provide low burst pressures from 5 psig (0.35 barg) using reverse buckling rupture disk technology. The LPS Rupture Disk (Bursting Disc), combined with the SRB-7RS® Safety Head, provides accuracy and reliability. The LPS uses SAF™ technology (Structural Apex Forming™) enabling very low burst pressures to be achieved with excellent opening characteristics.
