Beschreibung
Zusammenfassung:	An actuator suitable for use with a fluid flow control valve includes a frame, a bobbin, a coil and a plunger assembly. The frame is generally cylindrical and has a longitudinal axis. The bobbin, which is wound with the coil, includes a central cavity. The plunger assembly is received within the central cavity and includes a plunger portion and a rod portion. The plunger portion is formed of magnetic material. The rod portion may be snapped on the plunger portion to form the plunger assembly. The plunger assembly is configured to move within the cavity in response to an actuator control signal applied to the magnetic coil. Separating the plunger portion and the rod portion improves manufacturability as well as reduces the occurrence of rod damage.
