The XRX Series Rupture Disc is a high-performance safety device designed for pressure relief in various industrial applications. It features a domed, solid metal reverse buckling design with cross-scored grooves that ensure precise and reliable operation. This rupture disc is engineered to reverse on overpressure and opens by cutting along the cross-scored groove, preventing fragmentation and providing enhanced safety.
Ideal for isolating safety relief valves.
Up to 95% of the lower end of the burst pressure tolerance, providing excellent performance and longevity.
high cycle life compared to forward-acting rupture discs
Certified for use with gases or two-phase flows and capable of withstanding full vacuum conditions
Available in a wide range of materials, including SS316L, Hastelloy, Nickel, and Monel, making it suitable for both standard and exotic applications.
Available in sizes ranging from 25 mm (1 inch) to 300 mm (12 inches).
Handles burst pressures from 3 bar (G) to 70 bar (G), making it adaptable to various pressure requirements.
Designed to be non-sensitive to over-torque up to 30% of the recommended torque values, enhancing installation flexibility.
