An exhaust valve for inflatable diving equipment includes a valve body having an annular peripheral flange providing a sealing stable connection with a band of material along the edge of a passage opening in the delimiting wall of a hollow body, and a cylindrical collar surrounded by the annular flange and provided with coupling members to corresponding coupling members of a cover cap of the valve body. The cylindrical collar internally defines an annular valve seat that surrounds an opening communicating with the hollow body and that cooperates with a shutter provided on the side of the valve seat opposite to the internal space of the hollow body and stably stressed, in the closed position, against the valve seat, by an elastic element interposed between a wall of the cover cap and the facing side of the shutter. Optional displacement organs move the shutter from the stable closed position of the valve to an open position. The cover cap covers the valve seat and the shutter toward the outside and has a passage opening coupled with an interception and/or a deflection screen of particles or other suspended material, leaving free or openable a discharge passage.
