An electromotively actuated valve (10) is provided with a valve housing (11) on which an inlet connection (12) and at least one outlet connection (14) are provided, between which a flow duct (53) for a medium to be conducted through the valve (10) extends, and with an actuating member (31) which is actuated via an electric motor (54) and interacts with a valve seat surface (48) in order to close the flow duct (53), wherein the actuating member (31) is arranged coaxially in the electric motor (54) and is connected to the rotor (55) thereof in such a manner that rotation of the rotor (55) leads to an axial adjustment of the actuating member (31, 62). An external thread (59) is provided on the actuating member (31) and an internal thread (58), which is in engagement with the external thread (59), is provided on the rotor (55), and therefore the actuating member (31, 62) and rotor (55) form a helical gearing. |
