RD520 AXIUS® High Performance Rupture Disc

RD520 AXIUS® High Performance Rupture Disc

Smooth, Reverse-Acting, Lowest Burst Pressure

Designed to be used in aggressive chemical and pharmaceutical applications, the reverse-acting AXIUS® rupture disc is available in corrosion-resistant materials and has the tightest tolerances available.

  • Operating Ratio
    • 95% of marked burst pressures over 40 psig (2.76 barg) – ASME
    • 95% of minimum burst tolerance for burst pressures less than or equal to 40 psig (2.76 barg) – ASME and EN ISO 4126-2
    • 100% of minimum burst pressure over 40 psig (2.76 barg) – EN ISO 4126-2
  • Capable of up to 100,000 cycles with pressures ranging between full vacuum up to 95% of marked burst pressure (ASME) or 100% of minimum burst pressure range (EN ISO 4126-2) (up to 95% of minimum burst pressure for pressures below 40 psig)
  • Operates in both gas and liquid applications.
  • Can be ordered with an optional FEP or PFA fluoropolymer liner on the process side.
  • ASME Certified.
  • Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves.
