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
