ABSTRACT:
A slide gate valve assembly is provided wherein resilient means exert positive pressure to force a solid slide gate against the periphery of an aperture to establish a tight seal for retaining dry bulk particulate material in a container. Cam means are provided in the assembly to release the positive pressure on the side gate which may thereupon be removed from the aperture to dump the contents from the container.
