摘要

The valve (1) has a rotationally symmetrical valve body (3) movably arranged between an open position and a closed position in a valve housing (2), where the valve body is prestressed by a return spring (4). The valve body rests upon a housing-fixed seal seat (6) with a sealing element (5), in the closed position. The sealing element is fixed at the valve body by a clamping part. The clamping part is formed by a clamping ring (9). The clamping part is connected with a retaining dowel (7) of the valve body in a force-fit manner.
