BULGIN Standard Flow Reg End Flashback Arrestors
The Bulgin DGN - O Standard Flow Flashback Arrestor is a
German-engineered and manufactured safety device designed to deliver the
highest levels of safety, performance, and reliability in oxy-fuel welding,
cutting, and heating applications.
Every flashback arrestor is 100% function tested prior to leaving the factory. All assembled devices are tested with a flashback test, a leak test and a gas non-return valve test. This rigorous quality assurance
process provides complete confidence in product performance, safety, and
compliance.
Flashback arrestors are one of the most critical safety
devices in any oxy-fuel system. The Bulgin Flashback Arrestor range combines
proven German engineering, precision manufacturing, and comprehensive testing
to deliver dependable protection in demanding industrial environments.

Integrated Safety Features
NV – Gas Non-Return Valve
Prevents reverse gas flow and the formation of dangerous
mixed-gas conditions within the system.
FA – Flame Arrestor
Extinguishes flashbacks before they can propagate upstream,
protecting regulators, hoses, and gas supply equipment.
TV – Temperature Sensitive Shut-Off Valve
Automatically interrupts gas flow if excessive temperatures
occur, providing additional protection during flashback incidents.
DF – Dust Filter
Protects critical internal safety components from
contamination, maintaining long-term performance and reliability.
