Opti-Gard acts as a single disc solution across a complete line of sizes, materials, burst pressures and process conditions. Performing equally well with liquid, gas or vapour, Opti-Gard is the ideal multi-purpose pressure relief solution. It is non-fragmenting and can be used alone or in combination with a safety valve.
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
When installed as part of our stock rationalisation programme Opti-Gard can reduce stock holdings by up to 65%. This offers significant cost savings with reduced variance in inventory and installation, without affecting quality.
Opti-Gard with high-strength magnet
We also supply the Opti-Gard with a high-strength magnet for use in 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 up to 140°C. Standard rupture discs will not allow this, as the duplex stainless steel is magnetic and prevents the detector from functioning correctly.
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.
