Improvements introduced in the construction of passage valves for pipes, characterized by the fact that the flexible sleeve that is arranged inside to be pressed by the sealing element in its descent, is constructed, at least in the area of throttling with a section such that originates in the longitudinal sides of folding by crushing a certain angle that determines the line of superposition of both sides and prevents the material from the torsional stress.
