An aerial firefighting bucket assembly supported by a harness and includes an open bucket body with a bottom having an opening. A flexible tubular dump valve extends from the opening and has a free end defining a discharge port with a sealing lip defining two opposite lip portions. Pulleys or other roller mechanisms are mounted on one or the other of the lip portions, and end stops are mounted to the opposite lip portion such that each pulley faces an end stop. Flexible support lines from a control mechanism each pass through one pulley and terminate on the corresponding end stop. The lines when tensioned are drawn through the pulley and draw the corresponding end stop towards the pulley to bring the lip portions into sealing contact. The lines when slackened allow the lip portions to be forced apart for dumping water from the bucket.
