Elfab has further developed its
pressure-relief assembly range,
adding a design to prevent
environmental contamination in
severe process conditions.

The Double-Disc Assembly
comprises primary and secondary
bursting discs that are both reverseacting,
both forward-acting or now a
combination of the two, plus a
pressure gauge or switch to monitor
the space between the discs.

Should a chemical attack cause
pinholing of the primary disc, the
secondary disc prevents pollution of
the environment; the intermediate
pressure sensor alerts staff to the
need to replace the disc that has
operated.
