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

Flow control valve

A flow control valve, particularly an electromagnetic proportional directional flow control valve (), has a valve housing (), in which a control piston () is guided to be displaced axially. The control piston () actuates at least one fluid-conducting connection () between a fluid inlet () and an outflow opening (). An actuator part, in particular an armature (), can be actuated by an actuator, particularly a proportional magnet, and acts on the control piston (). A pressure detecting piston () serves for the action of the actuator part on the control piston (). The fluid inlet () is connected in a fluid-conducting manner by a pressure detecting channel () to a pressure detecting chamber () such that the fluid pressure prevailing in the pressure detecting chamber () loads the pressure detecting piston () and the control piston () with a force (F) in the direction of relief of the actuator, and a further fluid-conducting connection () between the fluid inlet () and a further outflow opening () is actuated.
