An automatic adjustable overpressure and manual exhaust valve (1) for diving dry-suits, said valve comprising a base member (2) provided with an opening (3), connected to the dry-suit inner volume, surrounded by an annular sealing surface (4), an autonomous closing member (5) positioned between said sealing surface (4) and a load transfer member (9) subjected to the load of a pressure setting spring (11). Said valve (1 ) further comprising a manual control member (19), axially movable perpendicularly to said opening (3) and interacting with said load transfer member (9) during the manual exhaust phase achieved by the axial movement, towards the dry-suit, of said control member (19) so as to cause the detachment of the load transfer member (9) from the closing member (5) and therefore the removal of the load of the setting spring (11) from the same closing member (5). |
