The Varec Biogas 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.
The extensive range of sizes and its corrosion resistant 356 T6 aluminum construction allows its use in most applications encountered in the typical tank farm, liquid storage facility, landfill or waste water treatment plant.
The 386 Series Regulator utilizes a large, spring loaded diaphragm, providing sensitivity while relieving excess gas with a minimal pressure drop. Set pressure is easily adjusted using the adjusting screw on top of the valve. An enclosed pointer provides quick visual indication of the set pressure.
