摘要： The invention relates to a control valve (10) for controlling a fluid flow, comprising a valve housing (22) and a positioning element (12) which can be translationally moved and which includes a shut-off portion (14, 70) and a throttle portion (16), with a valve seat being furthermore provided which includes a sealing portion (18, 44) and a throttle opening portion (28, 46), with the shut-off portion (14, 70) of said positioning element (12) being adapted to cooperate with the sealing portion (18, 44) of the valve seat (20, 40) so as to enable shut-off of the fluid flow, and with the throttle portion (16) of the positioning element (12, 54) being adapted to cooperate with the throttle opening portion (28, 46) of the valve seat (20, 40, 60) so as to enable the setting of a defined fluid flow, with at least the surfaces of the throttle opening (28) and the sealing portion (18, 44) being furthermore made of the same hard material. The invention is characterized in that the valve seat is designed as a valve seat insert (20, 40, 60) which includes the throttle opening portion (28, 46) and the sealing portion (18, 44), said insert being inserted into the valve housing.
