A proportional solenoid valve includes a valve body defining an inlet and an outlet for a fluid flow through the valve body and an armature that is moveable along a longitudinal axis from a first closed position to a second open position to control the flow of fluid through the valve. The valve further includes a flux can and an encapsulated coil assembly encompassed within the flux can. The encapsulated coil assembly includes a bobbin, a wire coil wound around the bobbin, and a non-conductive encapsulation layer that encapsulates the bobbin and the wire coil so as to electrically isolate the wire coil from the flux can and other conductive components of the valve. When the solenoid coil is energized, a magnetic field is created which causes the armature to move away from the first position against the valve body toward the second position, thereby opening the valve. The proportional solenoid further includes insulated wiring that is electrically connected to the wire coil, and a non-conductive encapsulation tower that encapsulates the insulated wiring so as to electrically isolate the insulated wiring from the flux can and other conductive components of the valve.

The actuator includes a movable body and a support body, first and second connecting bodies connected to the movable body and the support body, and a magnetic drive circuit. The movable body includes a first yoke including a first flat plate portion overlapping a coil from a Z1 direction, and a pair of first connecting plate portions extending from both ends of the first flat plate portion in a Z2 direction, and a second yoke including a second flat plate portion overlapping the coil in the Z2 direction and a pair of second connecting plate portions extending from both ends of the second flat plate portion in the Z1 direction. The first yoke and the second yoke are assembled by press-fitting the pair of second connecting plate portions into the pair of first connecting plate portions.
