Survival suits and other dry suits designed for wear on the surface have no inflation or dump valves as suit squeeze and achieving neutral buoyancy are not issues.

NASA spokesman Kyle Herring said it's possible ice could have formed and not been detected, even though heaters were installed on the waste water dump valve after the 1984 mission.

With the cabin structure sealed, cabin air was dumped overboard at a controlled rate through a dump valve and replaced with oxygen, from storage bottles, maintaining oxygen levels roughly constant.

Pan American stated at the time that the fuel dump valves underneath the wings likely vented vaporized fuel near the engines'exhaust ports, causing the explosion and loss of the flying boat.

At the time of installation of the Pratt & Whitney engines, dump valves were also installed to allow dumping of fuel if an emergency forced the crew to land shortly after takeoff.

Double dump valves are used to discharge a flow of material while at the same time serving as an airlock transition point to preserve the pressure differential above and below the valve.

"' Double dump valves "', also known as double flap valves or double flap gates, are a type of airlock valve commonly used in industrial applications as a component in bulk material handling applications.

Most dry suits are fitted with an auto-dump valve, which, if set correctly, and kept at the high point of the diver by good trim skills, will automatically release gas as it expands and retain a virtually constant volume during ascent.
19.
Most dry suits intended for scuba diving are fitted with an automatic dump valve, which can be adjusted to provide an approximately constant volume of gas in the suit, so the diver can concentrate on controlling ascent rate by venting the buoyancy compensator.

After the accident, the NTSB removed, inspected, and tested the right engine's ignition magneto and found it to be operating normally, concluding, " No mechanical or electrical discrepancies were found during the examination of the right magneto . " The inspection also determined that " All of the fuel cross-feed and fuel dump valves were in the closed position ."
