Description
A reverse-acting, semicircular scored rupture disc featuring a patented indentation to initiate failure and reduce reversal pressure.
The perfect solution for extremely low-pressure applications: an indentation that initiates failure and reduces the pressure at which reversal occurs, and a notched outlet ring that makes it easier for the rupture disc to open along a precise semicircular score, even at extremely low reversal pressures.
A breakthrough in rupture disc design: the LOTRX rupture disc. The LOTRX disc offers all the benefits of our scored reverse-acting discs, and more: an indentation that initiates failure to reduce the pressure at which reversal occurs and a notched outlet ring that makes it easier for the rupture disc to open along a precise semicircular score, making it the perfect solution for extremely low-pressure applications.
The LOTRX rupture disc features a failure-initiating indentation and a precise semicircular score, two characteristics that ensure clean, consistent opening patterns, even at low reversal pressure. It also includes a back-pressure support ring at the inlet, allowing it to operate under full vacuum conditions for burst pressure ratings of 5 psig (0.345 barg) and above.
The LOTRX is ideal for primary or secondary system relief protection and provides an effective means of fugitive emissions control when used to isolate a safety relief valve.
We test every LOTRX rupture disc order for compressible or incompressible relief conditions (as required by your application) to optimize rupture disc life and performance.
LOTRX rupture discs are manufactured and tested only for compressible relief conditions (gas or vapor) and may not perform properly in an incompressible (liquid) application.
Optional features:
Fluoropolymer outlet protective cover available for corrosion protection on the vent side of the rupture disc and holder in 1″ (above 4 psig) and 1 1/2″-8″ (all pressures).
Fluoropolymer coating available for corrosion protection on the process and vent sides of the rupture disc.
Cleaning for oxygen or chlorine service.
Stainless steel encapsulating rings are standard; optional ring materials are available.
