Valve for opening and closing flow medium pipeline, has casing with end surface, which is placed in round-shape by bushing unit, arranged in passage, by curved characteristics of inner area of bushing unit along flow direction of medium
The valve has a flow medium pipeline (1) with a passage (3) for a flow medium. An elastic surface unit (6) closes the passage by pressing a cross-section constriction and/or opens it by holding at a distance to the constriction. A casing has an end surface (8), which is placed in a round-shape by a bushing unit (9), arranged in the passage, by curved characteristics of an inner area of the unit (9) along a flow direction of the medium. - An INDEPENDENT CLAIM is also included for a method for manufacturing a valve and/or a bushing unit.
