Abstract
A valve assembly for a fuel tank includes a cage having a seat that defines an aperture and a spring latch that holds a poppet in an intermediate-open position, which spaces the poppet from a seat to allow fluid communication through an aperture. A method of operating a valve assembly due to a first-time fueling event is disclosed.
