A valve assembly may be used with a container for holding a fluid including a liquid and a gas. The valve assembly may have a chamber, inlet, and outlet. The chamber may provide an exhaust route for fluid from the container to the outlet. A check valve including a sealing member with a through hole may move between an open and closed position. In the open position, check valve may provide a main flow route for fluid leaving the internal chamber. The through hole may provide a limited return flow route for gas returning to the internal chamber when the check valve is closed. The valve assembly may include a breather check valve movable between a closed and open position in which it provides fluid communication between the exhaust route and externally of the housing. A filter may communicate with the breather check valve.
