Mumbai: European pressure relief specialist Elfab has been awarded a US patent for its reverse-acting rupture disc, Opti-GardTM SoLo. Opti-GardTM SoLo is now both a registered trademark, and has been granted patents, in the UK, EU and US.

The latest addition to Elfab’s industry-leading Opti-GardTM range, Opti-GardTM SoLo was developed specifically for low-pressure applications from two psig. Featuring a 95 per cent operating-to-burst-pressure ratio and a performance tolerance of just three per cent, Opti-GardTM SoLo offers the highest performance characteristics available for liquid, gas or vapour applications.

Tested to over 100,000 cycles, SoLo provides excellent cycle life and leak tightness. The addition of SoLo to Elfab’s existing Opti-GardTM range gives customers the opportunity of rationalising stock holdings by a typical 65 per cent.

Opti-GardTM SoLo comes pre-fitted with Integral Flo-TelTM, Elfab’s unique and completely reliable, non-invasive, magnetic burst-detection system. Unlike traditional membrane-type detectors, Flo-TelTM is fail-safe and operates only when a disc has ruptured, eliminating both false alarms and downtime in the event of a disc functioning.
