Regulator mounted gas safety devices / flashback arrestors (FBA)

Flashback arrestors for single cylinders, tapping points and distribution lines according to EN ISO 5175-1

Type: SRT, DGN, DG91N, DEMAX 5N

Flashback Arrestors

Highlights

  • Dust filter promotes long life
  • Gas non-return valve (check valve) prevents dangerous gas mixtures
  • Flame arrestor prevents flashback
  • Thermal cut-off valve prevents excessive temperatures

IBEDA offers dry-type flashback arrestors (FBA) with flame barriers, gas non-return valves (check valves), thermal shut-off valves and pressure-sensitive cut-off valves. The flashback arrestors SRT, DGN, DG91N and DEMAX 5N have the safety features of a flame barrier, gas non-return valve (check valve) and a thermal shut-off valve, thus meeting the requirements of a flashback arrester described in EN ISO 5175-1. DEMAX 5N is a dry-type high flow flashback arrestor (FBA) that uses several DGNs in parallel connection to give users a higher gas flow.

The models SR, DG, and DG91 have two built-in safety functions: a flame barrier and a non-return valve (check valve). The integrated flame barrier extinguishes the flashbacks and protects the valve to make sure it works safely even after a flashback. IBEDA offers flashback arrestors (FBA) for many industrial gases (Fuel Gases) such as acetylene, hydrogen, methane, natural gas, propane, propylene, butane, as well as oxygen and compressed air.

Always there, where high flow rates with low pressure drops are necessary for an on-going production process. The high flow rates quarantee a long product life with the highest level of safety.

Depending on type and design, they are applicable for

  • Welding up to 30 mm
  • Flame cutting up to 500 mm
  • Heating > 100 mm
