Description
The STAR X covers the low burst pressure ratings in the TRX line of scored, reverse-acting rupture discs. Learn more about the ULTRX, for high-pressure applications, or the MINTRX, for medium- to low-pressure applications.
The STAR X rupture disc has low burst pressures and includes a wide range of construction materials, as well as our precision failure-initiating indentations to precisely control disc bulging at exact pressures.

In addition, we also offer our HPX rupture discs.
This reverse-acting rupture disc is ideal for primary and secondary system relief protection or, when used to isolate a safety relief valve, provides an effective means of fugitive emissions control. Other system protection applications include installation on transfer piping, chemical reactors, pressure vessels, storage vessels and heat exchangers.
The STAR X incorporates a handling ring to reduce torque sensitivity. As with all our other reverse-acting rupture discs, every STAR X rupture disc is pressure tested at 90% before shipment. The STAR X rupture disc is compatible with the BDI alarm system.
The STAR X rupture disc features:
A safety ratio of 1.5 or less: designed so that a damaged rupture disc provides pressure relief at a pressure equal to or less than 1.5 times the disc's nominal burst pressure.
Operating capability in pressure cycles to full vacuum without additional vacuum support.
A standard manufacturing range of zero and an optional manufacturing range of -5% or -10%.
A permanent flow direction tag for visual verification of correct orientation.
Our precision failure-initiating indentation, to:
Weaken thicker materials to achieve low reversal pressures: the use of thicker materials also provides more robust discs that are more resistant to corrosion.
Ensure that the thicker material collapses properly and opens fully along the score line.
