• <br />• <br />VAPOR RECOVERY SHEAR VALVE <br />THE PETROLEUM INDUSTRY'S FIRST VAPOR <br />RECOVERY SHEAR VALVE IS CARB APPROVED. <br />B-1 with Replaceable Shear Top and <br />Support Bracket <br />*The patent -pending B-1 set <br />vapor recovery shear valve is <br />approved by the California Air <br />Resources board (CARB) and the <br />California State Fire Marshal. <br />•It is the first unit designed <br />specifically to meet the require- <br />ments of Sec. 79.911 of the lat- <br />est Uniform Fire Code. <br />*The B-1 set allows a 100 per- <br />cent flow, preventing any acci- <br />dental blockage or suffocation of <br />the vapor recovery system. Upon <br />impact, it immediately shears <br />and the valve is sealed off. It <br />cannot seal any other way. <br />*The B-1 has a cast iron body <br />and built-in pressure test port. It <br />comes with either a CARB- <br />approved Celcon® acetal <br />copolymer shear top or a CARB <br />and UL approved cast iron shear <br />top. Both tops are compatible <br />with all fuels. <br />•The CARB approved B-1 set and <br />its economically replaceable <br />shear top fit every containment <br />system brand and model in the <br />market. <br />6' <br />TO GASOLINE DISPENSER <br />T' NPT FEMALE <br />-1-1/2"NPT MALE <br />2-1/8" SHEAR SECTION (CELCON <br />OR CAST IRON) <br />SHEAR GROOVE <br />GASKET <br />TESTING POINT (1/8" NPT) <br />C/L <br />3-7/8" <br />BODY (CAST IRON) <br />SPRING (STAINLESS STEEL) <br />2-1/4" <br />SNAP RING <br />1-1/2" NPT FEMALE <br />. 2-1/2• 1 <br />The Model B-1 and/or B -I U Set <br />TO VAPOR <br />*Model B -IRT CARB approved Celcon® shear top replacement <br />•Model B-1RTU CARB and UL approved cast iron shear top <br />• <br />• <br />• <br />
