CONCOA 302 Series Regulator

The FSSCRN Nanoscored rupture disc is a compression or reverse-acting disc featuring precision micro-scored petals with four, six, or more radial scores. This design ensures fast, controlled opening while significantly reducing the risk of petal separation. Suitable for both low and high burst pressure applications, the FSSCRN performs reliably with gases and liquids when a gas cushion is present, even under cycling and pulsating conditions, without compromising safety margins.

In the event of overpressure, the disc activates within milliseconds and opens cleanly without fragmentation, making it ideal for protecting safety relief valves. It supports an operating-to-burst pressure ratio of up to 95% and delivers excellent corrosion resistance, which can be further enhanced with an optional PTFE lining. In many applications, the disc can also operate under full vacuum conditions without the need for additional supports, offering greater installation flexibility.
