Benefits:
- a large surface area flame arrestor FA of stainless 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
- a spring-loaded non-return valve NV prevents slow or sudden reverse gas flow forming explosive mixtures in the gas supply
Operation / Usage:
- in central gas supplies (behind the manifold pressure regulator or in a pipeline system)
- in thermal processing systems conforming to EN 746-2 (cutting machines, furnace supply equipment)
- WITT safety groups may be mounted in any position / orientation in pipelines / supply pipes
- the maximum ambient / working temperature is 60 °C / 140 °F
- gases: acetylene, natural gas, LPG, hydrogen, oxygen, ethylene, propane (more upon request)
