The SEWON Flame Trap Assembly combines a spring loaded thermal
valve with a flame arrester to prevent flame propagation in the
endurance burning condition of low pressure pipe lines.

The spring loaded thermal valve quickly closes when the fusible retainer
is melted in the presesnce of fire. It can be easily monitored the closed
position of seat from external view ports. The fusible retainer can be
replaced without disassembling entire unit.

Normally, Sewon STA FlameTrap is combined with horizontal flame
arrester Sewon Model SFH.
