Non fragmenting flat disc – type C

Applications :

  • Disc for liquids, gas and vapors
  • Operating ratio: 80% of the bursting pressure at 20°C
  • Lowest burst pressure can be realized (+25 mbar eff.)

Construction in accordance with directive 97/23/CE:

  • Between 2 laser-cut metal foils lies a PTFE sealing membrane
  • on fragmenting disc
  • Vacuum resistant
  • -80°C to +150°C because of PTFE sealing
  • DN15 à DN1200
  • Bursting tolerances: +/- 5% and +/- 15%

Materials : Stainless steel 316, Nickel, Hastelloy®, Inconel

Alternatives:

  • With detection plate
  • Bi-directional: bursting either in pressure or vacuum
  • PTFE lined on process side

Some other type of bursting discs (stainless steel, nickel, inconel, graphite…) may reach your need, feel free to contact us.
