Axius high performance bursting disc Smooth, Reverse-acting, Lowest Burst Pressure

Description

Designed to be used in aggressive chemical and pharmaceutical applications, the reverse-acting Axius® bursting disc is available in corrosion-resistant materials and has the tightest tolerances available. Enjoy cost and efficiency savings with this high performance disc.

  • Operate up to 95% of its marked burst pressure for burst pressures over 2.76 barg (40 psig), and up to 95% of the minimum of the burst tolerance at 2.76 barg (40 psig) and below.
  • Capable of cycling from full vacuum to 95% operating ratio in excess of 100,000 times, even at the lowest burst pressures available.
  • Disc seal and ring material: Hastelloy® C276 and 316/316L SST.
  • Operates in both gas and liquid applications.
  • Can be ordered with an optional FEP or PFA fluoropolymer liner on the process side, minimum burst pressure 2.07 barg (30 psig), maximum temperature 204°C (400°F).
  • ASME Certified.
  • Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves
