Specifying OPW 53V AND 30MV Ball Float Vent Valves <br /> IMPORTANT:Dimensions are for installations without Overfill Prevention Drop Tubes. See Drop Tube installation for <br /> reference on those installations. <br /> Specifying the Proper Length 53V Series Ball Float <br /> Step 1:Determine Dimension"X": Consult the tank chart(provided by the tank manufacturer)to determine the distance that <br /> corresponds to 10%of the total tank capacity <br /> Step 2:Determine Dimension"Y":Measure the dimension from the inside top of the tank to the top of the 4"threaded tank <br /> "bung"fitting. <br /> Step 3:Add measurements"X"and"Y".Then subtract 1/4"and round up to the nearest length ball float. <br /> Specifying the Proper Length 30MV Series Ball Float <br /> Step 1:Determine Dimension"X": Consult the tank chart(provided by the tank manufacturer)to determine the distance that <br /> corresponds to 308 gallons. <br /> Step 2:Determine Dimension"Y":Measure the dimension from the inside top of the tank to the top of the 4"threaded tank <br /> "bung"fitting. <br /> Step 3:Add measurements"X"and"Y".Then subtract 1/4"and round up to the nearest length ball float. <br /> Tank Manway Mounted Extractor Tank Top Mounted Extractor <br /> OPW 1-2100 (Typical) (Typical) OPW 1-2100 <br /> Spill Spill <br /> Container Container <br /> aDo Oo po Oo aD o4 aD oa aDo Oo po Oo aD o4 aD QQo <br /> .O a0 p.� �Oa oOv .O'O Doo O. .O p00.0 �Oa oOo .O'OOoo 0.� <br /> OPW 1711T, OPW 1711T, <br /> Vapor Recovery Vapor Recovery <br /> Cap Cap <br /> OPW 233 Series <br /> OPW 61 VSA Series, Extractor OPW 61VSASeries, <br /> Vapor Recovery Fitting OPW 233 Series Vapor Recovery <br /> Adaptor Extractor Adaptor <br /> Fitting <br /> To Tank 0 <br /> Vents <br /> To Tank a <br /> vents— <br /> Y <br /> Y <br /> X d d X <br /> m m <br /> OPW 53VM or 30MV, OPW 53VM or 30MV, <br /> Ball Float Ball Float <br /> Vent Valve Vent Valve <br /> OPEEO <br /> A DOVER T COMPANY <br /> P.O.Box 405003 *Cincinnati,Ohio 45240-5003 <br /> 1-800-422-2525 Domestically <br /> 513-870-3315 Internationally <br /> www.opw-fc.com <br /> Copyright,2002-OPW Fueling Components Inc.,Cincinnati,OH <br /> Printed in U.S.A.p/n H141 I1PA(7/02) <br />
