An electromagnetic proportional 2-way flow control valve (1) has a valve housing (2) in which a control piston (3) is guided to be displaced axially. The control piston (3) actuates at least one fluid-conducting connection (4) between a fluid inlet (5) and an outflow opening (6). An armature (8) can be actuated by a proportional magnet and acts on the control piston (3). A pressure detecting piston (9) serves as the actuator part on the control piston (3). The fluid inlet (5) is connected in a fluid-conducting manner by a pressure detecting channel (11) to a pressure detecting chamber (12) such that the fluid pressure prevailing in the pressure detecting chamber (12) loads the pressure detecting piston (9) and the control piston (3) with a force (F) in the direction of relief of the armature.
