Bulletin 74 1 ACE95JR April 2012 D102722X012 www fisherregulators com Type ACE95jr Tank Blanketing Valve Introduction Tank blanketing is the process of using a gas usually an inert gas such as nitrogen to maintain a slightly positive pressure in an enclosed storage tank Tank blanketing prevents a stored product from vaporizing into the atmosphere reduces product combustibility and prevents oxidation or contamination of the product by reducing its exposure to air Tank blanketing is utilized with various products including adhesives pharmaceuticals pesticides fertilizers fuels inks photographic chemicals and food additives Type ACE95jr valves are self contained fully balanced and used for accurate pressure control on tank blanketing systems These valves help control emissions and provide protection against atmospheric contamination Type ACE95jr valves maintain a positive tank pressure which reduces the possibility of tank wall collapse during pump out operations and prevents a stored product from vaporizing to atmosphere Fully Balanced Plug Design Reduces Inlet Pressure Sensitivity Stainless Steel Construction Available High Sensitivity Self Contained Bubble Tight Shutoff W8157 Figure 1 Type ACE95jr Tank Blanketing Valve Vacuum Settings Available Features Bulletin 74 1 ACE95JR 2 Specifications Sizes and End Connection Styles 1 2 NPT 1 x 1 2 NPT 1 N
