SAFE-GUARD-2 / MV93 - 2 FUNCTION FLASHBACK ARRESTORS

The GCE SAFE-GUARD-2 / MV93 range of basic flashback arrestors are available for connecting to regulators, hose lines and to torches.

Manufactured to EN730-1 and designed to prevent flashbacks in oxy/fuel systems, they includes the safety features of sintered flame arresting element (FA) to quench flashback plus non return valve (NV) to prevent reverse flow of gases.

FOUR MODELS ARE AVAILABLE FOR CONNECTION TO:

  • Regulator (model RP)
  • Hose line to Hose line (model TT)
  • Torch to hose line (model TF)
  • Torch threaded inlet/outlet (model FF)

SAFE-GUARD-1 / BV12

The GCE SAFEGUARD1 / BV 12 is a non-return valve that prevents reverse  ow of gases back into a hose. They are manufactured to our own approved design and the unique method of assembly eliminates the use of soldered or bonded joints. They are suitable to be used with Oxygen, Acetylene, Propane or Natural Gas and operate e ectively on either nozzle mix or injector type torches.

Max service pressure is 16 bar within a temperature range of -30°C to +50°C. The design is compact, not bigger than an ordinary hose nipple. Still the pressure losses involved are insigni cant and the set working pressure therefore stay unchanged. GCE SAFEGUARD1 / BV 12 is manufactured in accordance with European standard EN730-2.

GCE recommends that the GCE SAFEGUARD1 / BV 12 always are mounted on the torch inlet for both oxygen and fuel gas. Furthermore GCE recommend to check the function of the nonreturnvalve as a minimum every six month.
