Flashback Arrestors DIN EN 730-1 / ISO 5175-1

IBEDA develops and manufactures a wide range of safety devices (flashback arrestors with flame arrestors). The requirements on the safety devices are described in the DIN EN 730-1 standard. All IBEDA flashback arrestors undergo a leak test and a production flashback test after manufacture. IBEDA safety devices are independently certified by leading institutes, such as the German BAM and the American UL. Through the flame arrestor (flame barrier) and the gas non-return valve (check valve), these safety devices (flashback arrestors) with multiple safety functions provide optimal protection against flashback and gas return. The flame arrestor protects the gas non-return valve, ensuring that the gas flow is stopped in the event of a flashback. The safety devices are suitable for most technical gases such as Acetylene, Hydrogen, Methane, Propane and Butane as well as Oxygen and compressed air.

In addition to the integrated flame arrestor, safety devices (flashback arrestors) with multiple safety functions include at least one further safety feature.

Non-return valve yes yes yes
Flame arrestor yes yes yes
Temperature-sensitive cut-off valve yes yes
Pressure-sensitive cut-off valve yes

IBEDA safety devices help prevent:

  • Further gas flow in the case of pressure shocks
  • The entry of air or oxygen into the distribution line or single cylinders
  • Flashback which is the rapid propagation of flame down the hose
  • Further gas flow in the case of burnback
Pressure-sensitive gas cut-off valve (PV) No. 1

Pressure-sensitive gas cut-off valve (PV)

  • The pressure-sensitive cut-off valve stops the gas flow in the event of pressure shocks.
  • The safety device can be manually reset to continue working.

Flashback-Arrestor

Gas non-return valve (NV) No. 2

Gas non-return valve (NV)

  • The gas non-return valve prevents dangerous gas mixtures.
  • The gas non-return valve ensures the gas only flowing in the intended flow direction.
Flame arrestor No. 3

Flame arrestor (FA)

  • The flame arrestor cools the flame down to below the ignition temparature.
  • The flame arrestors prevents flashback.

Thermal cut-off valve

No. 4

Thermal cut-off valve (TV)

  • The thermal cut-off valve prevents excessive temperatures
  • The thermal cut-off valve closes automatically at a certain temperature and cuts off the gas flow.
