HO/HOV Bursting Disc Composite, Forward-acting


The cost-effective HO  bursting disc is a composite disc consisting of two components, the seal member and a slotted top that controls the burst pressure. With a fluoropolymer seal, this cost-effective bursting disc is a corrosion resistant, low pressure solution. The HOV bursting disc (high operating and vacuum) includes the addition of a vacuum support under the seal member.

  • In addition to the typical seal materials available, tantalum, titanium or other precious metals may be used when dealing with corrosive media.
  • 85% Operating Ratio
  • Gas or liquid service
  • Full vacuum rating (HOV)
  • Excellent corrosion resistance
Design Composite, Forward-acting
