<p>A valve is provided for use in controlling the flow of liquid out of a container, the valve comprising a valve body (10) having an inlet (11) and an outlet (12) for liquid. The valve also has a valve seat (13), a valve member (14) movable in the downstream direction onto the valve (13) to close the valve, and an operating device (20) for the valve member (14), the operating device (20) being positioned downstream of the valve member (14) and the valve member (14) being guided for translational movement between open and closed positions. The translational movement of the valve member (14) has a number of advantages, including the fact that liquid flow is symmetrical all around the valve member which decreases pressure drop and accelerates the discharge of liquid from the container. Other advantages are described in the specification.</p> |
