HO/HOV Series Rupture Disc

Brand: Fike Corporation

Fike’s HO Rupture Disc is a composite disc consisting of two components, the seal member and a slotted top.

In this configuration the slotted top section contains the seal and the seal transmits the pressure load to the top section.

The slotted top section controls the burst pressure of the disc and allows the use of fluoropolymer as a seal member.

In addition to the typical seal materials available, tantalum, titanium or other precious metals may be used when dealing with corrosive media.

The HOV Rupture Disc (high operating and vacuum) is constructed the same as the HO Disc with the addition of a vacuum support under the seal member.
Features
  • Can operate up to 80% of its marked burst pressure
  • Configuration requires a smaller amount of precious metal due to the top section controlling the burst pressure
  • Operates in both gas and liquid applications
