Bulletin 74 1 Y692 November 2014 Type Y692 Gas Blanketing Regulator System W5930 1 Figure 1 Type Y692 Low Pressure Gas Blanketing Regulator Introduction An Accu Pressure Gas Blanketing Regulator System reduces a high pressure gas such as Nitrogen to maintain a protective environment above any liquid stored in a tank or vessel when the liquid is being pumped out Also when the vessel is suddenly cooled causing vapors inside the vessel to contract the regulator system replaces the volume of contracting vapors with a volume of blanketing gas to prevent the internal vessel pressure from decreasing In both cases a Slight positive vessel pressure prevents outside air moisture and other contaminants from entering the vessel and the possible collapse of the vessel walls The Type Y692 Figure 1 is a direct operated regulator used for accurate pressure control on very low pressure blanketing systems Downstream pressure is sensed through a pitot tube installed in the lower casing of the regulator for units with internal pressure registration or through a downstream control line for units with external pressure registration The Type Y692 is available in NPS 1 1 2 and 2 DN 40 and 50 body sizes www fisherregulators com Features e Ease of Inspection and Maintenance The union nut connection between the body and actuator permits access to the disk and orifice by only removing the diaphragm casing assembly without
