The valve has a solenoid actuator and a position sensor providing an electric signal of the position of the solenoid armature. The solenoid is an electromagnet coil disposed on a plastic bobbin. The magnetic circuit contains a stator member having a flange disposed against a flange of the bobbin, and the position sensor has a plastic housing having a base that captures the stator member flange against the bobbin flange. The stator member flange contains apertures through which non-metallic material that joins with the bobbin flange passes to join with the position sensor housing base, thereby uniting the bobbin and the position sensor housing in assembly capturing the stator member flange. The assembly may be fabricated by an insert molding method or a method in which joining material is melted.

1. An exhaust gas recirculation (EGR) valve for an internal combustion engine comprising an inlet port at which exhaust gas enters the valve, an outlet port at which exhaust gas exits the valve, a valve element for selectively restricting exhaust gas flow between the inlet port and the outlet port, an electric actuator comprising an electromagnet coil disposed on a non-metallic bobbin having a flange bounding one end of the coil and an armature forming a portion of a magnetic circuit that is operated by the coil for selectively positioning the valve element, and a position sensor providing an electric signal of armature position, the magnetic circuit further comprising a stator member having a flange disposed against the flange of the bobbin, and the position sensor further comprising a non-metallic housing having a base that captures the stator member flange against the bobbin flange, wherein the stator member flange comprises apertures through which non-metallic material that joins with the bobbin flange passes to join with the position sensor housing base to thereby unite the bobbin and the position sensor housing in assembly capturing the stator member flange.
