AP Valves makes a self-sealing model. I only know about it from the Web site, but I think there's someone here who uses one.

That would be me...I use an APValve Buddy model SMBC. It has a self-sealing flap. Works great but it's a bugger to get the water out!
I use it as a signaling device as well as a lift bag.
