Upstream Pressure Regulator PB Series
The PB series pilot operated upstream pressure control valves are pressure relief valves which combine sensitivity with the stability of the controlled pressure. These valves can react to very small changes in controlled pressure. Due to the pressure loaded design, differential pressure across the main valve diaphragm is minimum. Hence, these valves are also suitable for high pressure setting. Different pilot and main valve actuators are available to cover wide range of pressure and flow requirements.

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).
