M <br /> OPW 53VML " BALL FLO9APV ENT VALVES <br /> l� Introducing the new (DPW 53VNIL 3" Ball Float Vent <br /> Valve for faster delivery flow rate... <br /> Federal EPA technical standards for overfill prevention of petroleum underground <br /> storage 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 bail 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 01PW 53VML 3" Series Valves <br /> feature: <br /> ♦ Faster Delivery Rate-3"size <br /> increases vapor flow and reduces <br /> delivery time. <br /> ♦Ball and Stem Float Design-ball <br /> seats properly when the liquid rises B <br /> to a predetermined level. A <br /> s Duragar&Coated Body-to <br /> provide protection against corrosion. <br /> ♦ Easy Installation-existing <br /> extractor fittings are retrofrttable to <br /> 3" size by removing the existing <br /> cage and ball float. <br /> ♦Easy Extraction-allows for tank <br /> testing. <br /> a Variety of Lengths- to meet your C <br /> specific UST application. <br /> Ordering Specifications and Dimensions <br /> Warning Product No. A B C <br /> Example Tank Applications, <br /> OPW Overfill Warning Systems in, mm. in. mm. in. mm. installed as shown fig, 1 <br /> Pumping systems,not suction pump <br /> should only used on submerged 53VML-3080 I I%" 280 8 280 3T 92 Does not meet EPA 90%requirement <br /> systems. 53VML-3110 14%" 356 11 296 3W 92 Does not meet EPA 90%re uirement <br /> OPW Overfill Warning Systems *53VML-3120 15%6" 381 12 305 39" 92 Does not meet EPA 903 re uirement <br /> should only be used on Gravity Drop 53VML-3140 11Ye" 432 14 356 39" 92 Does not meet EPA 90�ement <br /> systems, DO NOT use where Pump Off 53VML-3160 1916" 483 16 401 N' 92 8' dia,,fiberglass and steel tanks, <br /> Unloading is used, single wall <br /> Materials 53VML-3180 21N" 534 18 458 N 92 8' din.,fiberglass,double wall <br /> Pipe nipple:steel <br /> Coating:Duragard" <br /> Ball:stainless steel <br /> Q P VV <br /> °°E°°Fs°R°Fs°°°°• P.D.Box 405003•(inannati,Ohio 45240-5003•Telephone:(5131870-3219•(8001422-2525♦Fox:(800)421.3291 — - <br /> o Copyright 1992 OPW Fueling Components/A Dover Resources Company,Printed In USA 9/92 <br />
