Flat Rupture Discs

Flat Rupture Discs

For protection against overpressure and vacuum in gases and liquids

Flat rupture discs from REMBE^® offer you fragmentation- free opening across the full width of the vent. They can be produced in virtually any size, for extremely low pressures from 15 mbar and with very low burst tolerances.

For protection against overpressure and vacuum in, for example, storage vessels and low pressure systems. Also suitable as a secondary safety device alongside breather valves. This rupture disc is designed to work at standard operating ratios of up to 50 %* of the minimum response pressure. It is installed directly between flanges and, due to its half holes, suitable for all flange systems. A wide range of materials can be used as seals.

^{* Depending on the specific application}

Your advantages:

Requires less space than safety valves due to lower installation height.
Available for all flanges and in any nominal width.
No holder required for installation.
