Description

The 97161 Pressure Relief and Flame Trap Assembly combines a back pressure regulator, a thermal operated valve and a horizontal flame arrester to maintain upstream pressure and effectively inhibit flame propagation in low pressure gas lines.

The back pressure regulator maintains a preset upstream pressure, the flame arrester effectively quenches internal flames, and the fusible element positively shuts off flow in emergency flame conditions.
Standard materials of construction include an Aluminum Body and BUNA-N diaphragm. The large diameter diaphragm reduces line bounce for smoother gas flow. The 97161 has simple spring loaded settings for easy field adjustment. The components are easy to access providing for simplified cleaning and maintenance. It’s aluminum and stainless steel components withstand severe process environments. The 97161 is especially designed for hydrogen sulfide and hot, wet methane which are the main components of digester gas streams in for example, municipal waste water treatment facilities.
