Embodiments of the present disclosure relate generally to valves that provide controlled inflation. The valves are designed to allow inflation of one or more inflatable devices and to stop inflation once a desired inflation level has been reached. This can allow the valve to be used with a single inflation source in order to inflate a plurality of inflatable devices. In a specific example, this disclosure provides systems and methods for inflating an ejector bag for door-mounted or fuselage-mounted inflatable evacuation slides or slide/rafts used for evacuating passenger vessels, such as aircraft. Other examples relate to sustaining the inflation of individual tubes that communicate with one another in evacuation slides, evacuation slide/rafts, life rafts and/or other inflatable devices.
