4420 V421 <br />V42e <br />Patente <br />4,163,41 <br />V420V421 V422 V423 V425 <br />VENT VALVE ASSEMBLY—Universal Vent Valve Assemblies allow man! - <br />folding of tank lines. When used in conjunction with Universal Roat Vent <br />Valve 37 or 38, the Vent Valve Assembly restricts the vent system when <br />fuel level forces the ball to seat; slowing delivery rate dramatically, alerting <br />driver to -stop tank fill. Polymeric -coated cast iron body. V421 includes V423 <br />Cage Assembly (used with 37); V420 does not include V423 Cage Assembly <br />(used with 38). The Vent Valve Assembly mounts on the UST flange and <br />secures and property positions the Roat Vent Valve in the tank The com- <br />bination of V421 Vent Valve Assembly and 37 Roat Vent Valve is recom- <br />mended for use in conjunction with vapor recovery systems, where the <br />underground vent piping of similar products may be manifbided. In this <br />application the Roat Vent Valve will reduce product crossover. <br />Model # Part Size Weight (lbs.).
