RD500 ATLAS® High Performance Rupture Disc

RD500 ATLAS® High Performance Rupture Disc

Higher Pressure, High Performance

ATLAS offers higher pressure capability, while still featuring high performance benefits including a 95% operating ratio, liquid or vapor service, back pressure resistance and unrivaled cycling capability. Higher burst pressures of up to 1500 PSIG (103.42 BARG), makes ATLAS the endurance workhorse of the G2 Technology line of products.

  • 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 100,00 cycles with pressures ranging between full vacuum up to 95% of marked burst pressure (ASME) or 100% of the minimum burst pressure range (EN-ISO 4126-2) (up to 95% of minimum burst pressure for pressures below 40 psig (2.75 barg))
  • Available in multiple materials and flange ratings
  • Operates in both gas and liquid applications
  • Ideal for sour gas applications
  • Can be ordered with an optional FEP or PFA fluoropolymer liner on the process side
  • Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves
