정보

WITT Safety groups for reliable protection against dangerous reverse gas flow and flashbacks in accordance with DIN EN ISO 5175-1. For applications with high flow rates. Every safety group 100% tested.

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)

Maintenance:

  • annual testing of the non-return valve, body leak tightness and flow capacity is recommended
  • safety groups are only to be serviced by the manufacturer

Options

  • connection: two-sided female thread (G-; NPT-; RC-thread)

Approvals
Company certified to ISO 9001 and PED 97/23/EC Module H
