Abstract

Step valve, provided with a shut-off disk rotary closing inside a tubular box, whose peripheral edge is bent towards the axis of rotation, and which acts in cooperation with an annular zone within said box and coaxial with the light thereof by means of a sealing element, angularly bent in radial section, said sealing element being fixed at an edge to said closing disc or to the box, and being provided with a lip which in the closed position is in contact with a planned sliding surface respectively in the case or in said closure disc, along an annular sealing area with a pressure that guarantees the hermetic sealing, increasing the closing pressure when the pressure of the fluid increases on the concave face of the characterized seal element because the joint element can oscillate axially with respect to its clamping plate of the convex face or the concave to obtain a hermetic seal that increases when a pressure of the fluid in any direction of passage thereof, so that the envelope curve of all the positions of the joint element encloses the annular sealing area between said lip and the sliding surface, said joint element being constituted with respect to its shape and/or selection of material, so that when the pressure of the fluid takes place on, the convex face of said seal element opposite the free end of the lip increases the pressure thereof due to its oscillation being greater than the pressure due to the fluid, acting on said lip in the sense of separating it from the sliding surface.
