Rupture Discs / Reverse Acting


HPX® Rupture Disc
offered with a choice of 90% or 95% Operating ratio and tested in excess of 250,000 cycles.

The HPX® Rupture Disc is a scored, reverse acting rupture disc. It is a differential pressure relief device that provides an instantaneous full-open, non-reclosing design for protecting equipment, vessels and systems from an overpressure condition. TheHPX® Rupture Disc is a high precision reverse acting rupture disc that offers proven performance in excess of 250,000 cycles at 95% operating ratio.

TheHPX® Rupture Disc excels in fully liquid systems as well as gaseous or partial gas/liquid systems.
Full opening occurs in liquid or gaseous systems.

STAR X®


The STAR X Rupture Disc is designed to provide protection at even lower burst pressures than the ULTRX or MINTRX rupture discs. It has Continental Disc's patented nonsymmetrical failure initiating indents, to precisely control disc buckling at a predetermined pressure. The STAR X Rupture Disc incorporates a handling ring to reduce torque sensitivity. It is specifically designed for low pressure applications that require operating ratio of up to 90% of the disc's rated (marked) burst pressure.

MINTRX® Rupture Disc

The MINTRX Rupture Disc has many of the same benefits as the ULTRX Rupture Disc, but is specifically designed to operate at lower burst pressures. When the patented precision controlled indentation on the rupture disc surface initiates the reversal action, full opening will occur..

SANITRX® Rupture Disc

The SANITRX® Rupture Disc is a semicircular-scored reverse acting rupture disc designed to provide instantaneous overpressure protection in sanitary environments. Engineered exclusively for applications concerned with product purity and trouble-free equipment sterilization, the SANITRX® Rupture Disc provides overpressure protection for sanitary systems, equipment, and vessels. This solid metal rupture disc is ideal for primary and/or secondary system relief protection and isolating a system or safety relief valve from leakage or permeation.

SANITRX® LP Rupture Disc


For applications that require lower pressures with reduced flow resistance, Continental Disc offers the SANITRX LP® Rupture Disc. This new rupture disc was designed specifically to provide the same features as the original SANITRX® Rupture Disc, but with the added benefit of lower available burst pressures.
Plus, through the benefit of using our on-site ASME Accepted Flow Test Laboratory, the SANITRX LP® Rupture Disc has been designed to have one of the lowest KR flow resistance factors available in a rupture disc of any design - from any manufacturer.
