Abstract A valve with presetting of the amount of throughflow, particu- larly a thermostatic valve for hot water central heating, comprises a cylindrical housing bore (9) of which the base (8) comprises the valve seat (2) and the cylindrical circumferential surface (10) comprises a fixed opening (11) communicating with a connector (12). An insert (14) is guided only in the housing bore (10) and is connected by way of a rotary coupling (38) which permits play to a setting element (15) which serves for rotary adjustment. The circumferential wall (41) of the insert (14) abuts the base (?) with its end under spring force and circumferentially bounds a control orifice (42) which co-operates with the fixed opening (11). The control orifice is covered up to at least one residual through- passage (45) to the valve chamber (4) by a skirt (44). The insert can be adjusted by small forces. The danger of jamming is substan- tially eliminated. Fig. 1.
