Beschreibung
Zusammenfassung:	An electrohydraulic valve including an electromagnetic actuator assembly; and a hydraulic assembly, wherein the electromagnetic actuator assembly and the hydraulic assembly are arranged in axial alignment along a longitudinal axis, wherein the hydraulic assembly includes a valve housing in which a valve piston is arranged axially movable along the longitudinal axis, wherein the electromagnetic actuator assembly includes an actuator housing, a coil configured to generate a magnetic field and an armature that is arranged axially movable along the longitudinal axis to position the valve piston, wherein a connection is formed between the electromagnetic actuator assembly and the hydraulic assembly, wherein the actuator housing is formed by an encasement of at least the coil with a synthetic material through injection molding, wherein a circumferential annular groove is formed in which a seal element is positioned that seals the electromagnetic actuator assembly between the hydraulic assembly and the electromagnetic actuator assembly.
