Abstract
A valve assembly for transferring fluid from a fluid supply tank to a fluid holding tank. The valve assembly includes a housing having a first port for communication with the fluid supply tank and a second port for communication with the fluid holding tank. A drum is rotatably mounted in the housing and has a passageway therein. The passageway has an opening located at each end thereof positioned on an outer surface of the drum for alignment with one of the ports in the housing. The drum is rotatable between a flow position in which the openings are aligned with the ports to permit fluid flow from the fluid supply tank to the fluid holding tank and a shut-off position in which one of the openings is not aligned with the ports to prevent flow from the supply tank to the holding tank. The valve assembly further comprises an actuator for rotating the drum within the housing between the fluid flow and shut-off positions. The housing is sealingly engageable with the fluid supply tank around a periphery of an aperture in the tank for sealingly closing the aperture in the tank.
