Eaton announced its Vehicle Group has introduced a new zero-leak Compact Combo Valve that safely vents harmful evaporative fuel vapors in the tank by stacking a Fill Limit Vent Valve (FLVV) and a new Zero-Leak Grade Vent Valve (GVV). key benefit of the Compact Combo is reduced fuel vapor permeation. The smaller footprint of the stacked valves allows for a tighter seal when welded to the tank, in turn reducing permeation. This innovative configuration reduces the products footprint by 20 mm, which decreases potential leak paths and provides fuel tank manufacturers more design flexibility. The Zero-Leak GVV fulfills all government-mandated requirements for zero-leak vapor valves. The new Compact Combo Valve technology reduces hydrocarbon emissions with 98% efficiency during the vehicle refueling process and allows manufacturers to meet vehicle hydrocarbon emissions standards while the vehicle is parked. The Compact Combo Valve has several unique design features that increase valve functionality to meet both tank and customer requirements. These features include a seal that reduces liquid leak in static venting conditions, as well as the ability to change the shut-off height of the FLVV through component substitution. Eaton also offers an added slosh baffle feature for vehicle applications involving aggressive driving dynamics that may cause shifting liquid fuel to leak.
