Opti-Gard rupture disc

Opti-Gard is a high-performance reverse acting rupture disc. With a high operating ratio of up to 95% combined with an industry-leading burst tolerance of +/-3%, it enables exceptionally high performance that supports process safety and efficiency.

Opti-Gard features a smooth surface finish and can be supplied with an optional fluoropolymer liner on the process and/or vacuum side. It withstands full vacuum and high levels of back pressure without additional vacuum support to ensure the maximum free-flow area on burst.

We supply Opti-Gard as standard with a magnet for our non-invasive burst detection system, Flo-Tel. Flo-Tel offers a practical, reusable solution for detecting when a rupture disc has functioned. The sensor is non-invasive to the process and is therefore unaffected by downstream pressure fluctuations or corrosion.

After an overpressure event, the sensor does not need replacing, which eliminates the need for expensive re-wiring costs and maintenance planning. Our dual-certified dual-certified Exd/EXia/b system Flo-Tel XD offers the same non-invasive burst detection for hazardous and explosive environments.
