On modern drysuit
used for scuba-diving 2 valves is always used, an
inlet and an outlet valve, the inlet valve is
often place on the chest of the suit, and is
letting air from the air-supply into the suit,
where the air ‘pumps’ up the suit, and
prevent ‘suit-squeeze’. The air is also
helping keeping the suit warm, the heat from the
diver s body, is
warming up the suit. The valve us operated by
pressing a button in the valve, the air is then
let into the suit.The
out-valve is normally placed on the left arm, the
most important is that the valve can be the
highest point on the suit, and let air out. The
valve can be either manual for automatic, on the
manual type, the diver must press a button on the
valve for letting air out, on the automatic type,
an outer ring can be adjusted, to let the valve
open a a given overpressure in the suit, the
automatic valve can also the activated manually.
