VAPOR RECOVERY & OVERFILL PROTECTION ACCESSORIES <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 Size Weight(lbs)' Height Width <br /> V420-0000 0'z 0" 18.4 8' 61/a* <br /> V420-0020 0"x 2" 16.2 8" 65/8' <br /> V420-2020 2'x 2" 15.7 8" 65/8" <br /> ✓ V420-0030 0"x 3" 18.0 8" 65/8' <br /> V420-3020 3'x 2" 16.7 8' 6518" <br /> V420-3030 3'x 3" 17.6 8" 6518' <br /> V421-0000 0"x 0' 18.4 8" 65/8' <br /> V421-0020 0'x 2" 16.2 8' 6518' <br /> V421-2020 2"x 2" 15.7 8" 6518" <br /> V421.0030 0"x 3" 18.0 8' 6518" <br /> V421-3020 3"x 2' 16.7 8" 6518' <br /> V420 V421 <br /> V421-3030 3"x 3' 17.6 8" 6518" <br /> •Allows manifolding of tank lines • Polymeric-coated cast iron body <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 /> Model# Size Bleed Hale Size Weight(lbs.)
