VAPOR RECOVERY & OVERFILL PROTECTION ACCESSORIES <br /> VENT VALVE ASSEMBLY-Allows manifolding of tank lines. Can be used in <br /> 1 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 /> 1 . <br /> Model# Port Size Weight(lbs.)

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 /> �s <br /> the transport driver to stop product drop. <br /> Model# Size Bleed Hale Size Weight(lbs.)
