Abstract
An outlet valve assembly is provided for a railway tank car. The valve is mounted at the bottom of the tank car for discharging downwardly between the tracks. The valve is operable between the closed position to occlude flow through the valve and an opened position to permit flow through the valve. A shaft is operably connected to, and extends from, the valve on a horizontal axis normal to the length of the tank car for being rotated on the axis to operate the valve between the closed and opened positions. A handle is connected to the shaft at a predetermined distance from the valve, and the handle extends generally radially outwardly from the shaft. The valve is operated between the closed and opened positions when the handle is swung through an arc from an initial orientation to a final orientation. The length of the handle and the predetermined distance between the valve and handle connection is selected such that the handle can be swung between the initial and final orientations by a person standing upright beside the tank car outside of the tracks.
