A valve assembly for use with a container for holding a fluid comprising a liquid and a gas, the valve assembly comprises a housing having an internal chamber therein and an inlet and an outlet to and from the internal chamber, the internal chamber in use being in fluid communication with the container and providing for an exhaust route for fluid from the container to the outlet. The valve assembly further includes a check valve including a sealing member movable between a check valve open position, and a check valve closed position, the sealing member having one or more through holes therein, the check valve when in the check valve open position providing for a main flow route for fluid leaving the internal chamber via the outlet, the through hole(s) in the sealing member providing for a limited return flow route for gas returning to the internal chamber via the outlet when the check valve is in the check valve closed position. The valve assembly further comprises a breather check valve movable between a breather valve open position in which it provides fluid communication between the exhaust route and externally of the housing, and a breather valve closed position, and a filter which is in gas communication with the breather check valve for filtering gas before the gas enters the internal chamber and container. |
