KSRRK Reverse Dome Shear Rupture Disc

Reverse dome shear type rupture disc with disc and knife integrated, installed in the FDC standard holder. A knife ring on the upper disc shears the dome as it inverts. It carries the widest temperature range in the FDC flange range, and the datasheet notes it is easier to handle than the KSRR.

Design

Reverse dome shear type; disc and knife integrated; shear actuated structure ruptured by the knife ring attached to the upper disc as the dome is inverted
