Regulator End

Regulator end flashback arrestors are safety devices fitted to the outlet of a regulator. They incorporate a number of features designed to protect upstream equipment from damage in the event of a flashback or sustained burn back. Of importance, all regulator end models incorporate a thermal cut-off valve as a failsafe, to shut off the flow of gas, eliminating the fire.

Standard Flow Quick Action Coupling - Boxed (Model: DGNDK)

Gallery

The DGNDK model flashback arrestor offers all of the functionality of the DGN standard flow model, with the addition of a quick action coupling and pin. The pin connects to the hose while the flashback arrestor remains on the regulator. The hose can then be connected to the flashback arrestor via the coupling pin. This allows for quick connection and disconnection of the hose without the need for spanners. The coupling and pin meet ISO 7289 and the double 'O' ring design ensures no leakage. Also different coupling pins are available as spare parts for regulator end flashback arrestors.
