Zusammenfassung:	A throughflow regulating valve has a second throttling point (13) in addition to the first throttling point (7) formed by the valve seat (6) and closure member (4). This second throttling point is formed with the aid of a recess (11) in the circumferential wall (10) of a rotary insert (8) cooperating with an aperture (12) in the valve housing (1). The closure member is actuated by a servo element (17) in a servo element housing (14) which is rotatably connected to the valve housing (1) but fixed to the rotary insert (8). In this way, the second throttling point (13) can be conveniently set. The setting is recognisable from the outside. Fig.1
