Válvula de retención con elemento optimizado de cierre

摘要

The valve (1) has a single-part closing element (3) arranged in a displacable medium by a discharge medium. The closing element lies against a profile seal (5) of a sealing section in a closing position. The closing element is guided via a bearing (10), which is concentrically arranged in a valve housing. The closing element comprises a zone, in which an outer contour exhibits flow optimized form, and another zone, in which the outer contour exhibits a calotte form. The zones are arranged in series and change-over with each other in a circulating manner.
