ABSTRACT:
A gate valve assembly and a frame assembly for mounting the gate valve assembly on the discharge opening from a railway hopper car. The gate valve assembly includes an operating assembly for movement of a valve member within the gate valve assembly between a first, closed position and a second, open position. A locking mechanism is mounted on the frame assembly to maintain the gate valve assembly in its first closed position when the associated railway car is subjected to large impact forces. The operating assembly includes a lock striker which may be moved longitudinally relative to the valve member to deactivate the locking mechanism while the valve member remains in its closed position. The frame assembly also provides an enhanced seal or barrier to prevent materials from escaping when the gate valve assembly is in its closed position.
