VAPOR RECOVERY & OVERFILL PROTECTION ACCESSORIES <br /> 11 11111� 111111 i <br /> VENT VALVE ASSEMBLY-Allows manifolding of tank lines. Can be used in <br /> conjunction with Universal Float Vent Valve 37 or 38, for overfill protection.Also <br /> reduces product crossover in manifolded vapor recovery systems. V421 includes <br /> V423 Cage Assembly (used with 37);V420 does not include V423 Cage <br /> Assembly (used with 38). <br /> Model Port S¢e _ VJe�ght(lbs} height Width <br /> .._ r�_S.O._.�.• ht <br /> V420-0000. 0"x 0" 1:8.4 8" 65 is <br /> V420-0020 0"x 2' 16.2 8' 65/e" <br /> V420.2020 2"x 2" i 5.7 8' 65is" <br /> V420.0030 0'x 3" 18.0 8" <br /> V420.3020 3'x 2' 16.7 8" fi=le" <br /> V420.3030 Y x 3' 17.6 8' 65ie" <br /> V421.0000 0"x 0' 18.4 8" 65is" <br /> V421-0020 0'x 2' 16.2 8' 65/s' <br /> v421-2020 2'x 2' 15.7 8' 65/e' <br /> V421-0030 0"z 3" 18.0 8' 65'e" <br /> V421.3020 3"x 2' 16.7 8' 65/e" <br /> V420 V421 1'421.3030 3"x 3" 17.6 8' 65is" <br /> • Allows manifolding of tank lines • Polymeric-coated cast iron bay <br /> • Easy mounting on UST flange • Standard 4" inlet and outlet <br /> • Properly positions the Float Vent Valve <br /> FLOAT VENT VALVE- Used in conjunction with the Model V421 Vent Valve <br /> Assembly to protect against overfill of USTs by signaling the transport driver when <br /> the tank is filled to 90% capacity, in accordance with EPA guidelines. Fuel levels <br /> force the stainless steel ball to seat tightly against a specially-designed valve seat, <br /> which restricts the venting system and slows delivery rate dramatically, alerting <br /> the transport driver to stop product drop. <br /> All S1 a Weight(ibs.)
