	The "PressureExternal" value ~~is a measure~~ of the atmosphere surrounding the active vent.		The "PressureExternal" value limits the pressure of the atmosphere surrounding the active vent, preventing operation if reached.

	Contrary to popular belief, both values are enforced, so the Active Vent comes with the functionality of a Pressure Regulator and simultaneously also Back Pressure Regulator. Note that setting these value and changing the Mode afterwards is ill-advised: Changing the Mode always resets both values to their defaults (~~101~~/0 for pumping into the room, 0/50 for pumping into the pipe), so they must be set (if at all) after setting the Mode.

	The "PressureExternal" values can also be inconvenient on worlds like ~~Loulan~~ whose atmosphere is well above 101kPa. Manually-operated airlocks can not equalise the pressure within the airlock during the exit cycle to the Loulan atmosphere pressures. Without equal pressures you can not prevent wind currents from occurring when opening airlock doors. The active vent has no effect when the external pressure within the airlock surrounding the active vent is already >101kPa. When the pressure is <101kPa the vent will stop when it reaches 101kPa.
