The invention relates to a blocking element (1) for fluid media. The position of said blocking element, which has a peripherally located hinge axis (2), can be modified according to the flow. According to the invention, an influencing member (3) is provided within or on the blocking element (1). Said influencing member (3) has certain properties in order to respond to sensors which are disposed in the vicinity and react to changes in position. The invention further relates to a non-return flap comprising a blocking element (1) that can be moved from a sealing position in which the blocking element rests against a valve seat into an open position, and vice versa, according to the flow. The blocking element (1) comprises an influencing member (3) which has certain properties in order to respond to sensors that are disposed in the vicinity and react to changes in position. |
