Opti-Gard High-Strength Magnet

High-performance rupture disc for use with duplex holders

Opti-Gard (High-Strength Magnet) is a technically advanced reverse-acting rupture disc specifically designed for use with 22cr and 25cr  duplex holders. The high-strength magnet means you can still use our unique, non-invasive burst detection systems Flo-Tel and Flo-Tel XD. Standard rupture discs will not allow this, as the duplex stainless steel is magnetic and prevents the detector from functioning correctly. Elfab’s specially developed high-strength magnet overcomes this problem and enables accurate signalling up to 140°C.

Key Features

• For use with 22cr and 25cr duplex holders

• High-strength magnet ensures compatibility with Flo-Tel and Flo-Tel XD up to 140°C

• Industry-leading 3% tolerance

• Manufactured to ISO4126 or ASME VIII (UD stamp available)

• Up to 97% operating ratio possible

• Optional fluoropolymer liner on the process and/or vacuum side

• Withstands full vacuum and high levels of back pressure without additional vacuum support. This ensures maximum free-flow area on burst
