A flow control valve, in particular in the form of an electromagnetic proportional 2-way flow control valve (1), having a valve housing (2), in which a control piston (3) is guided such that it can be displaced axially, which control piston (3) actuates at least one fluid-conducting connection (4) between a fluid inlet (5) and an outflow opening (6), wherein an actuator part, in particular an armature (8), which can be actuated by an actuator, in particular in the form of a proportional magnet, acts on the control piston (3), is characterized in that a pressure detecting piston (9) serves for the action of the actuator part on the control piston (3), and in that the fluid inlet (5) is connected in a fluid-conducting manner by means of a pressure detecting channel (11) to a pressure detecting chamber (12) in such a way that the fluid pressure which prevails 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 actuator.
