An aerial valve for a liquid container (e.g., a bag or a tank) suspended or otherwise carried by a firefighting aircraft includes an axially compressible tubular diaphragm. To open and close the valve, a motorized leadscrew raises and lowers a flow stopper relative to a discharge opening. The tubular diaphragm creates an air chamber above the flow stopper, so the full weight of the liquid in the container is not bearing down against the flow stopper. Thus, less force is needed to lift the flow stopper from its closed position, making the valve easier to open. Some examples of the aerial valve include features that make it wear resistant, easy to service, reprogram remotely, inexpensive to ship, and useful as a replacement for existing valves.
