public class RuptureDisk
extends ThrottlingValve

RuptureDisk class - represents a rupture disk (bursting disc) safety device.

A rupture disk is a non-reclosing pressure relief device that bursts at a set pressure and remains fully open. Unlike a safety valve, a rupture disk is a one-time use device that cannot reseat after activation.

Typical applications:

• Primary relief for rapid pressure rise scenarios
• Backup protection in series with safety valves
• Protection for highly corrosive or fouling services
• Emergency relief for runaway reactions
