The GCE SAFE GUARD 1 / 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 SAFE GUARD 1 / BV 12 is manufactured in accordance with European standard EN730-2.
GCE recommends that the GCE SAFE GUARD 1 / 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.
