Continental Disc's solid metal, scored, reverse acting rupture discs are differential pressure relief devices that provide an instantaneous fully-open, non-reclosing design for protecting vessels, equipment, and systems from an overpressure condition. The ULTRX®, MINTRX®, STAR X®, and LOTRX® rupture discs offer a wide range of pressures and reliable features, including: • A ZERO MANUFACTURING RANGE as a standard • Recommended maximum operating pressure of 90% of the rated (marked) burst pressure. • Solid metal design in a variety of available materials for corrosion resistance • Encapsulating rings, which minimize torque sensitivity and provide a leaktight metal-to-metal seal (handling ring for STAR X Rupture Disc) • Permanently attached 3-dimensional flow direction tag, alignment pins, and J-Hook for proper rupture disc and holder orientation
