A valve assembly () for an aircraft water supply system. The valve assembly () comprises a valve member (), an electrical motor (), and a mechanical returning mechanism (). When electrical power is provided, the motor () can be controlled to move the valve member () from a first position and to a second position. The mechanism () is operably connected to the valve member () and mechanically biases it towards the first position. If a power loss occurs when the valve member () is in the second position, the returning mechanism () non-electrically (e.g., mechanically) returns the valve member () to the first position.

An inflatable aircraft evacuation slide system includes a primary valve, a bust disk and a valve leakage trap operatively disposed between the primary valve and the burst disk. The valve leakage trap comprises a small exhaust vent opening into a flow restriction orifice in the gas path between the primary valve and the burst disk. In operation, when the aircraft emergency exit is opened in the armed condition, the primary valve opens and pressurizes the chamber until the burst disk ruptures allowing inflation gases to pass through the flow restriction orifice to inflate the inflatable evacuation slide. Because there is a substantial pressure drop across the flow restriction orifice, the presence of the valve leakage safety vent in the orifice does not result in significant loss of inflation gas needed for inflating the inflatable evacuation slide. In the event of leakage past the primary valve, however, the valve leakage trap safely vents the leakage pressure to the atmosphere.
