Rupture discs for hygienic applications
A rupture disc is a pressure safety device that protects a system against overpressure and/or underpressure (vacuum), preventing explosion or implosion. It is an engineered weak spot that ensures the rest of the system remains intact.
The rupture disc is deployed in a closed system to create a pressure relief opening at a certain pressure, preventing the pressure or vacuum from becoming too high. Pressure safety is essential because the consequences of an accident can be fatal.

CDC (Continental Disc Corporation) is a manufacturer and market leader of rupture discs for sanitary and industrial applications. CDC employs innovative and patented designs, traceable materials of the highest quality, and is ISO 9001 certified.
Functions
The CDC rupture disc can have two functions:
Primary safety function in a system (the rupture disc provides protection against over/underpressure)
Secondary function (the rupture disc is used as a complement to a safety valve)
Connections
The CDC rupture discs can be used in a Tri-Clamp®, NovAseptic® connection (or alternatives); making them easy to deploy in existing systems.
