1 TT 53VML 3-" BALL FLOATr <br />NtroCILICitl!" the new 0PN ;3VN1L 3" Ball Float Vent <br />`alve for faster deliN erg floe- 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 return/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: <br />4 Faster Delivery Rate - 3" size <br />increases vapor flow and reduces <br />delivery time. <br />e Ball and Stem Float Design - ball <br />seats properly %� hen the liquid rises <br />to a predetermined level. <br />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 />E Variety of Lengths - to meet your <br />specific UST application. <br />OPW Overfill Warning Systems <br />should only be used on submerged <br />pumping systems, not suction pump <br />systems. <br />OPW Overfill Warning Systems <br />should only be used on Gravity Drop <br />systems. DO NOT use where Pump Off <br />Unloading is used. <br />Materials <br />Pipe nipple: steel <br />Coating: Duragard' <br />Ball: stainless steel <br />e DMEfI AESOUWCES COGVep> <br />Ordering Specifications and Dimensions <br />Product No. <br />A <br />B <br />C <br />Example Tank Applications, <br />in. <br />mm. <br />in. <br />mm. <br />in. <br />mm. <br />installed as shown, fig. l <br />11'/,6" <br />280 <br />8 <br />280 <br />3%" <br />92 <br />Does not meet EPA 90% requirement <br />_53VML-3080 <br />53VML-3110 <br />106' <br />356 <br />11 <br />298 <br />3X" <br />92 <br />Does not meet EPA 90% requirement <br />53VML-3120 <br />15'/,6' <br />381 <br />12 <br />305 <br />3%" <br />92 <br />Does not meet EPA 90% requirement <br />53VML-3140 <br />17%b" <br />432 <br />14 <br />356 <br />3%" <br />92 <br />Does not meet EPA 90% requirement <br />53VML-3160 <br />19%6' <br />483 <br />16 <br />407 <br />3%" <br />92 <br />8' dia., fiberglass and steel tanks, <br />single wall <br />53VML-3180 <br />21'/6' <br />534 <br />18 <br />458 <br />3%" <br />92 <br />8' dia., fiberglass, double wall <br />P.O.
