Downstream Pilot Operated Pressure Regulator B3 Series
The B3 Series is twin pilot operated regulator system used for highly accurate pressure control in very low pressure blanketing applications. This reduces a high pressure of inert gas, such as nitrogen to preserve a protecting environment above any liquid stored in a tank or vessel, when the liquid is being pumped out or also when the vessel is rapidly cooled, causing vapors inside the tank vessel to contract. The Regulator System rushes in blanketing gas to replace the volume of contracting vapors to prevent the internal tank pressure from decreasing. A small positive pressure prevents outside air, moisture & other contaminants from entering the tank & the possible collapse of the tank. The B3 Series regulator system includes the Main regulator (MPCV), Pilot feed regulator (PFR), Response adjusting device (RAD) & Sensing pilot (PSCV).
