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 presence 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.
