OPW 53V ftLL FLOAT VEIFT VALVES <br /> OPW Overfill Warning, Systems <br /> The OPW 53VM ball float vent valve extractor and related mounting hardware <br /> can be installed in several configurations. In all cases,it is recommended than an <br /> OPW extractable fitting be installed; <br /> +To allow the valve to be removed and a plug installed for tank tightness testing. <br /> + To allow the valve to be removed for tank servicing activities. <br /> OPW Overfill Warning Systems can be used with dual-point vapor recovery sys- <br /> tems or when the only location where vapors can leave the tank is via the float-vent <br /> valve assembly. <br /> 7 <br /> KIN. <br /> tTllT 1911-f 56fIAV i STT 11B <br /> 111-AV rW 61A <br /> tOM 1 <br /> 11-TCS <br /> Z33-Z33-M50YwM SS4M <br /> Al Sl-VM <br /> TO VMI <br /> 51+7 II <br /> m-SD To V� FpT To Y_ <br /> wlh S1VM � <br /> �7 <br /> Stage I Vapor Recovery and Separate Combined Stage I and Stage II Vapor Coaxial Stage I Vapor Recovery and <br /> Product Drop Connection Product Fill <br /> Stage II vapor recovery is not This illustration shows an OPW The OPW 233MSD(including the <br /> required in this system and utilizes the 233MSD(including the OPW 53VM) OPW 53VM) is used in a system-A <br /> OPW L611AV for Stage I vapor recov- with a 1611A adaptor for Stage I seal closes off the coaxial vapor return <br /> ery mounted above a 233SD(includes vapor recovery.The manifolded vent line from the tank through the coaxial <br /> OPW 53VM).
