safety devices for Propylene service E460 WITT Flashback Arrestors for reliable protection against dangerous reverse gas flow and flashbacks according to EN 730-1 / ISO 5175. Every Arrestor 100% tested. The best Flashback Arrestors in the world ●● for torches of burners: Model E460 ●● a large surface area flame arrestor FA of stainless ●● WITT Flashback Arrestors may be mounted in any steel construction extinguishes any dangerous flashback entering the device in any direction ●● a temperature sensitive cut-off valve TV extinguishes sustained flashbacks long before the internal temperature of the arrestors reaches a dangerous level (not on E460) sudden reverse gas flow forming explosive mixtures in the gas supply ●● a filter at the gas inlet protects the arrestor against dirt contamination, extending the service life (only RF53N, 85-10, 85-30) ●● Flashback Arrestors are used to protect gas cylinders and pipeline outlet points (hoses and any equipment) against dangerous reverse gas flow and flashbacks ●● for pipeline outlets and single cylinders with high users Technical Data 70 °C / 158 °F Maintenance ●● annual testing of the non-return valve, body leak tightness and flow capacity is recommended ●● WITT is happy to supply special test equipment ●● Flashback Arrestors are only to be serviced by the manufacturer.
