Reverse Domed Scored Rupture Disk is designed with a cross or circular scored line build-up on the concave side of the disk. The disk reverses and opens along pre-weakened cross-scored lines to provide a full relief opening at its burst pressure.

Types

? Welded Rupture Disk (YCH): good seal performance, suitable for high sealing conditions

? Cross-scored and circular-scored rupture disk
