Instrumentation & Electrical : Rupture Disc / Reverse Buckling Bursting Disc
Type of Rupture Disc :    Forward Acting Bursting Disc   |   Reverse Buckling Bursting Discs   |   Explosion Vent Panels

MARSTON Rupture Disc is a non-reclosing pressure relief device actuated by inlet static pressure by the bursting of a pressure containing disc.

MN / MO Maxivent Assemblies.
Usually a single foil disc which has the pressure applied to it's convex side. The dome inverts and is completely expelled from it's holder and stopped by an arrestor.
RBH Assemblies.
Usually a single foil disc which has the pressure applied to it's convex side. The dome inverts and opens along a peripheral groove. It's designed to be retained by it's hinge portion.
LRBH Assemblies
Usually a single foil disc which is designed specifically for liquid duties. The pressure is applied to it's convex side. The dome inverts and opens along a peripheral groove. It's designed to be retained bny it's hinge portion.
SRBH Assemblies
This disc has two membranes. A load-bearing slotted metallic membrane and a weaker, usually fluoropolymer, seal membrane giving a non-fragmenting design suitable for low bursting pressures.
GRB Graphite Disc Assemblies
A unique disc manufactured from pure graphite powder. It's suitable for high temperatures and extremely low bursting pressures. This disc will fragment on rupture.
