A valve assembly includes a body engageable with a container, an internal cavity, and a vent outlet. A wall divides the internal cavity into a first chamber and a second chamber, the first chamber being between the bottom end of the body and the wall, and the second chamber being between the top end of the body and the wall, in communication with the vent outlet. An umbrella valve is coupled to the wall and has a central passage and an umbrella portion. The umbrella portion is positioned within the second chamber and is configured to engage a top side of the wall. The umbrella portion is configured to deform away from the top side of the wall to vent a gas along a first pathway from the first chamber to the vent outlet in response to pressure within the first chamber exceeding a cracking pressure of the umbrella valve.
