ABSTRACT:
A reverse buckling disk has an annular retaining flange for mounting in a flow passageway. The annular retaining flange is integrally formed with a central domed portion having a concave side and a convex side. The disk has a predetermined material thickness and domed height for establishing a rated pressure at which the central domed portion reverse buckles. A metal cutting element or knife is fixedly attached to at least a portion of the convex side of the central domed portion in surface-conforming relationship. The metal cutting element has a thickness greater than the thickness of the disk material and has at least one knife point thereon for cutting the disk as the central domed portion reverse buckles at the rated pressure.
