Single Layer Rupture Disc BT

SINGLE LAYER RUPTURE DISCS – THE FATHER OF ALL RUPTURE DISCS

The rupture disc that started it all many decades ago. Even now, this forward acting  rupture disc is still a good choice for simple applications with medium to high pressures, such as in pumps, in the petrochemical and chemical industries or in hydraulics. The standard operating ratio is up to 70 %* of the minimum response pressure.
The burst pressure is determined by the tensile strength and thickness of the material. Also available with integrated vacuum support for total vacuum resistance.

*Depending on the specific application

Your advantages:

  • Easy to use.
  • Wide range of materials available.
