An inflation control system for an inflatable may comprise a compressed fluid source, a valve module, a temperature sensor, and a controller. The valve module is connected to the compressed fluid source and configured to control a flow of gas to the inflatable. The temperature sensor measures an ambient temperature and outputs the ambient temperature measurement. The controller is operably coupled to the valve module and configured to receive the ambient temperature measurement and determine an open-valve time based on the ambient temperature measurement, the open-valve time being a duration of time the valve module is in an open position.

An inflation valve arrangement includes an actuation cavity housing connected to a pneumatic valve, the actuation cavity housing comprising an actuation cavity and a piston rod extending from the actuation cavity at least partially into a main fluid channel of the pneumatic valve in an initially extended position for securing the pneumatic valve in a closed position. The arrangement further comprises a solenoid actuated pressure cartridge connected to the actuation cavity housing. The solenoid actuated pressure cartridge comprises a self-contained source of actuation gas. In response to the solenoid actuated pressure cartridge being energized, the solenoid operated pressure cartridge is configured to release the actuation gas from the pressure cavity into the actuation cavity, thereby retracting the piston rod into the actuation cavity, and opening the pneumatic valve body to release a source of inflation gas to an inflation device.

An aircraft exterior light unit may comprise a magnetically controlled fluid drain valve configured to expel liquid water from the light unit. The valve may include a permanent magnet configured to induce a magnetic flux circuit that generates a magnetic force configured to close the valve. The valve may be configured to open when the pressure inside the light unit exceeds the magnetic force. As the valve opens and expels the water, the pressure within the light unit may decrease, equalizing with that of the external environment. As the magnetic force generated by the magnet increases as the valve is open and the water expelled, the magnet may be configured to close the valve once more. As such, the magnet may be configured to control a self-acting fluid drain valve in an aircraft exterior light.

A flush valve includes a housing having a first end and a second end, a piston stem extending between the first end and the second end, a piston stem fore end coupled to the piston stem, a first O-ring and a second O-ring defining a control chamber therebetween, and a solenoid valve in fluid communication with the control chamber. The piston stem fore end is positioned toward the second end when in a closed position. In an energized state, the solenoid valve charges a pressurized gas into the control chamber, pushing the piston stem toward the first end and into an open position.
