Elfab has been awarded a US patent
for its reverse-acting rupture disc –
Opti-Gard SoLo. SoLo is now a
registered trademark and has been
granted patents in the UK, the EU
and the US.

The device was developed for low
pressure applications from 2psig and
has a 95% operating-to-burstpressure
ratio and a performance
tolerance of just 3%. Tested to more
than 100,000 cycles, it affords good
cycle life and leak tightness. The
addition of SoLo to Elfab’s range is
said to give customers the
opportunity to rationalise stock
holdings by a typical 65%.

Opti-Gard SoLo comes pre-fitted
with Integral Flo-Tel, Elfab’s noninvasive,
magnetic burst detection
system that operates only when a
disc has ruptured, eliminating both
false alarms and downtime in the
event of a disc functioning.
