A 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 product’s 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.
“Eaton's world-class engineering teams are leading the way in developing innovative and highly efficient fuel vapor management products,” said Brian Contat, business unit director, Fuel Emissions, Eaton’s Vehicle Group. “As evaporative emissions reduction and vehicle standards become more stringent, Eaton’s fuel emissions products deliver a competitive advantage worldwide that helps our customers achieve or exceed upcoming emissions regulations.”
The new Compact Combo Valve technology reduces hydrocarbon emissions with 98 percent 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.“We can use short or long FLVV housings, depending on the application, for maximum permeation reduction,” Contat said. “We are able to cover all shut-off height requirements to vent above the shut-off valve when the main refueling valve is closed and the GVV shut-off height remains constant and optimized.”
