The Oseco 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. 

Since there are no knife blades, the flow is unrestricted.

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