i <br /> OPW 53V BALL FLOAT VENT VALVES <br /> OPW 53VML Ball Float Vent Valves, when uislalled in an OPW 233V Extraclor <br /> Filling, farm a system that helps prevent product mixing:end rneels the. Federal <br /> EPA's 90% flow restriction requirement for ovcrlill prevc116011 of underground stor- <br /> age tanks. <br /> When the UST is filled to a predclermined level, the stainless steel ball Iloat rises <br /> to seat lightly against a specially designed valve seat. This restricts the flow of <br /> vapors back t0 the delivery transport or tank vent. 'file pressure created in the UST <br /> by the vapor flow restriction works against the head of liquid remaining in the deliv- <br /> ery transport and (loses to reduce the incoming flow rale. <br /> The OPW 53VML.,provides consis- Unique[Matures: <br /> tent performance and long service I.Vapor flow,orifice-properly sized <br /> life: l' '� i to cause a"slow down"effect and <br /> Proven Concept -the basic ball + reduce delivery flow. <br /> Iloat concept has been proven in 1 2.
