0 P 53VML 3 " BALL FL0ArFVENT VALVES <br /> E' Introducing the new OPW 53VNIL 3" Ball Float Vent <br /> Valve for faster delivery flow rate... <br /> Federal EPA technical standards for overfill prevention of petroleum underground <br /> stora¢e tanks allow the use of ball float vent valves that restrict the delivery flow <br /> when the fuel has reached a predetermined level in the UST. <br /> An OPW 53VML Ball Float Vent Valve can be located in the vapor retum/extrac- <br /> tor fitting of underground storage tanks. <br /> When the UST is filled to a predetermined level,the ball float rises to seat against <br /> the body. Vapor flow out of the tank is restricted and delivery flow rate is dramati- <br /> cally reduced.This flow restriction is a warning to the transfer operator,or delivery <br /> attendant so that he may take action to stop the delivery process. <br /> All OPW 53VML 3" Series Valves <br /> feature: o <br /> ♦ Faster Delivery Rate-3"size <br /> increases vapor flow and reduces <br /> delivery time. ° <br /> ♦ BalI and Stem Float Design -ball <br /> seats properly when the liquid rises B <br /> to a predetermined level. A <br /> s Duragard"Coated Body-to <br /> provide protection against corrosion. <br /> ♦ Easy Installation-existing <br /> extractor fittings are retrofittable to <br /> 3" size by removing the existing <br /> cage and ball float, <br /> + Easy Extraction-allows for tank <br /> testing. <br /> Variety of Lengths to meet your C <br /> specific UST application. <br /> Ordering Specifications and Dimensions <br /> Warning Product No. A B C Example Tank Applications, <br /> OPW Overfill Warning Systems in. mm. in, mm. in. mm. installed as shown,fig. i <br /> should only be used on submerged 53VML-3000 1118" 280 8 280 39" 92 Does not meet EPA 90%requirement <br /> pumping systems,not suction pump <br /> systems. 53VML-3110 1418" 356 11 298 3X" 92 Does not meet EPA 909 requirement <br /> OPW Overfill Warning Systems *53VML-3120 15V 381 12 305 31" 92 Does not meet EPA 90%requirement <br /> should only be used on Gravity Drop 53VML-3140 17V 432 14 356 31" 92 Does not meet EPA 90%requirement <br /> systems.
