An inflatable object has a curved section, and an improved valve featuring a flexible chute that has an inner edge connected to said inflatable object and is rollable and unrollable between a rolled-up closed position and an unrolled open position. The inner edge is connected to said inflatable object along said curved section at a location and orientation operable to use pressure inside said inflatable object to resist unrolling of said flexible chute from the rolled-up closed position, thereby imparting a self-locking functionality to the valve.
