CONCOA 325 Series Regulator

The FSY90N Nano Scored Rupture Disc is a reverse-acting, micro-scored compression disc designed for high reliability and precision pressure relief. Its convex shape remains stable under operating pressure and only inverts at the set reverse pressure. Capable of operating at up to 95% of its burst pressure, the disc withstands thousands of pressure cycles without loss of performance. When activation occurs, it opens fully within milliseconds along the scored pattern, producing no fragments.

FSY90N discs are less affected by temperature fluctuations than conventional rupture discs, making them ideal for processes with wide temperature variations. They are suitable for gas and liquid applications (with a gas cushion where required) and are commonly used to protect pressure relief valves. A broad selection of materials and thicknesses provides excellent corrosion resistance, with optional PTFE lining available for enhanced chemical protection. Vacuum support is not required.
