Rupture Disk
The original rupture disk (bursting disc) manufacturer shaping the growth of pressure relief devices for over 80 years.

REV/REV-7R Replaceable Element Disks

The REV™ type disk is suitable for applications where vacuum conditions exist and when the burst pressure is less than 22psig (1.52 bar).
  • REV-7R™ Safety Head
    A locating pin on the REV™ disk mates with a location hole in the safety head outlet thus eliminating incorrect installation. The REV-7R™ safety head is provided with an integral non-opening vacuum support on the process side of the safety head
  • Vacuum
    Supports are designed to maximize venting capacities while maintaining structural strength
  • Flange Ratings
    The safety heads are designed to fit between all standard international pipe flanges, ANSI, DIN, AFNOR, BS, JIS and to nestle within the flange bolts
  • Material
    Safety heads are available in impregnated graphite or 316SS as standard
  • Patented: US 5,121,847 Japan 2611105
