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. The dirt filter may be replaced by competent staff Operation / Usage single Flashback Arrestor ●● the maximum ambient / working temperature is Approvals Company certified according to ISO 9001 and PED 97/23/EC module H CE-marked according to: - PED 97/23/EC Length [inch] Brass Elastomer Connections available on request manufactures mixing, metering and control equipment as well as analysing systems and safety equipment for all common gases Product Information ●● a spring loaded non-return valve NV prevents slow or position /orientation ●● only one piece of equipment may be connected to a
