Rupture Discs

A rupture disc is a pressure relief device that bursts at a set pressure to release excess pressure and protect equipment. It has no moving parts, provides a fast and leak-tight response, and must be replaced after activation. Commonly used in chemical, oil & gas, and power industries for safe pressure control.

Why Choose Rupture Discs from ADYAA?

Instant Response

Rupture discs provide immediate pressure relief with no delay, as they burst the moment the set pressure is reached, ensuring rapid system protection.

Zero Leakage Design

Being a solid, sealed membrane, rupture discs offer 100% leak-tight sealing before activation — ideal for toxic, flammable, or high-purity applications.

Compact & Lightweight

They have a simple, space-saving design, making them easy to install in tight spaces and integrate with existing systems or relief valves.

Cost-Effective Safety Solution

Compared to safety valves, rupture discs are economical while still providing high reliability and protection for critical equipment.

Compatibility & Integration

Can be used alone or in combination with safety valves, enhancing protection and extending valve life by preventing corrosion and leakage.
