Inverted rupture disc STAR X™

flat seatreverse actingstainless steel

The STAR X rupture disc has low burst pressures and includes a wide range of construction materials as well as our precision failure-initiating indent to precisely control disc buckling at exact pressures. The STAR X covers 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 mid- to low-pressure applications. 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 emission control. Additional system-protection applications include installation in 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 proof pressure-tested to 90% prior to shipment. The STAR X is compatible with the BDI alarm system. The STAR X rupture disc features: -A safety ratio of 1.5 or less – designed so a damaged rupture disc will provide pressure relief at or less than 1.5 times the rated burst pressure of the rupture disc -Operational capacity in pressure-to-full-vacuum cycling without additional vacuum support -A standard zero manufacturing range and an optional -5% or -10% manufacturing range -A permanent flow-direction tag for visual verification of proper orientation -Our precision failure-initiating indent, to:
