Elfab”s Opti-Gard line of bursting discs has been developed specifically for low-pressure applications from two PSIG. The new Opti-Gard SoLo, the result of a unique design and manufacturing process, is a reverse-acting bursting disc, featuring a 95 percent operating-to-burst pressure ratio and a performance tolerance of just 3 percent. Supports liquid, gas, and vapor applications. Pre-fitted with integral Flo-Tel, Elfab’s reliable, noninvasive, magnetic burst-detection system. Unlike traditional membrane-type detectors, Flo-Tel is failsafe and operates only when a disc has ruptured, eliminating false alarms and unnecessary downtime. The disc fits all standard Opti-Gard and Hygienic Opti-Gard holders and is supplied in corrosion-resistant Hastelloy as standard; other materials, including stainless steel, are available upon request. Tested to over 100,000 cycles.
