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(Ibs.)

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 Hole Size Weight(lbs.)
