Safety Device, Biogas Solution

The Groth Model 8400A Pressure Relief and Flame Trap Assembly accomplishes two purposes. It will maintain a predetermined back pressure in order that only surplus gas is flared and it inhibits a possible flame flashback of the flare into the gas control system.


A fusible element that is rated at 260 F precludes valve shut-off unless contacted by flame. The visual indicator provides operator with easy adjustments. The proven spiral wound, crimped ribbon flame element provides the best flame quenching performance with the least pressure drop.

– Simple upstream pressure regulation allows for accurate pressure relief
– Adjustable set pressure for easy process pressure relief adjustment
– Prevents pipeline deflagration from damaging tanks, pipelines, and other process equipment
– Corrosion Resistant throughout
