OsecoElfab’s PLR is a high performance reverse buckling rupture disc designed for very low-pressure applications. The PLR is ideal for gas or liquid applications requiring burst pressures down to 2 PSIG.

The armored construction protects the disc from damage that often affects the performance of other low-pressure rupture discs.

The PLR is excellent for protecting and isolating safety relief valves (SRV). Due to the large opening characteristics, in some sizes an extended outlet holder may be required when installed directly under an SRV.
