PCR

OsecoElfab’s PCR is a cross-scored, reverse- buckling rupture disc. Reversal occurs when the disc reaches the rated pressure and it opens along the score lines.

The cross-scoring allows the disc to achieve higher burst pressures without fragmentating.

The PCR is excellent for relief valve isolation (gas and vapor service) and excels in extreme cycling or high vacuum/back pressure applications. The PCR is commonly used in SF6 switchgear units.
