RD320 Reverse Acting Rupture Disc

RD320 Reverse Acting Rupture Disc

The Benefits of G2 Manufacturing Technology for Common Pressure Relief Applications

Engineered with Fike’s patented G2 Manufacturing Technology, the RD320 reverse-acting rupture disc provides accurate and reliable burst pressure protection in most chemical and refinery applications. The pre-engineered RD320 rupture disc is available in corrosion-resistant materials for nearly any application.

Product Detail

  • Operate up to 90% of its marked burst pressure for burst pressures over 40 psig (2.76 barg), up to 90% of the minimum for burst pressures less than or equal to 40 psig (2.76 barg) (ASME and EN ISO 4126-2); 95% of minimum burst pressure over 40 psig (2.76 barg) (EN ISO 4126-2)
  • Capable of cycling in excess of 10,000 times from full vacuum to 90% marked burst pressure (ASME); 95% of the minimum burst pressure range (EN ISO 4126-2) (up to 90% of minimum burst pressure for pressures below 40 psig)
  • Backpressure: 100% of specified burst pressure.
  • Operates in both gas and liquid applications.
  • ASME Certified.
  • Disc seal and ring material: 316/316L SST; Hastelloy® C276 and INC625.
  • Can be ordered with an optional FEP or PFA fluoropolymer liner on the process side, minimum burst pressure 30 psig (2.07 barg), maximum temperature 400°F (204°C).
  • Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves.
