SRX Rupture Disc

SRX Rupture Disc

Scored, Reverse-Acting, Low Burst Pressure

The reverse-acting, SRX rupture disc has a cross scored design for use with vapor services only. It offers a superior service life in heavy pulsating and cyclic duty, and performs reliably under less than ideal installation conditions.

  • The score configuration controls the disc opening and enables the disc to rupture without fragmentation.
  • Effective when used to isolate Safety Relief Valves
  • Will sustain process operating pressures as high as 90% of the stamped disc rating or 95% of the minimum burst pressure
  • Withstands full vacuum, or back pressure service in magnitudes equivalent to the stamped burst pressure.
  • Special seating configuration allows this rupture disc to perform reliably, even under less than ideal installation conditions.
  • All manufacturing ranges are below the specified burst pressure
  • Materials of construction include: 316/316L SST, Inconel®, Monel®, Nickel, and Hastelloy®. Protective coatings such as fluoropolymer and polyurethane are available to enhance corrosion resistance.
  • Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves
