Overview

The 386 Series Back Pressure Regulator is intended for use in low pressure gas systems. It operates normally closed and will open when the upstream pressure reaches the regulator’s predetermined settings. It is typically used to control flow of gas to the flare by utilizing a large, spring loaded diaphragm while relieving excess gas with minimal pressure drop. The pressure setting can easily be adjusted using the adjusting screw on top of the valve. An enclosed pointer provides quick visual indication of the set pressure.
