QUICK DEFLATION VALVE
The new valve allows greater deflation than the one
traditionally used in the inflator with ID hose. Its primary
function is to allow gradual or quick bag deflation: in fact,
the valve, equipped with servomechanism, is operated
through a cable directly by the by-pass slider.
Its secondary function is to act as an additional
overpressure valve, by checking that the bag is not
excessively inflated and does not exceed the maximum
interstage pressure.
The following figures show the O-ring replacement
which, for safety reasons, must only be carried out by
technical personnel authorized by CRESSI-SUB.
