A relatively rugged and simple solenoid-actuated valve ( 100 ) is disclosed having a coil assembly ( 150 ), including a bobbin ( 152 ), a winding ( 160 ) for generating a magnetic field, and a flux path bracket ( 162 ). A fixed pole piece ( 110 ) extends into the axial volume defined by the bobbin. The coil assembly may be encased in a plastic outer body ( 101 ). An armature ( 120 ) is slidably disposed in the axial volume and a valve seat ( 130 ) closes the opposite end of the axial volume. A conical spring ( 140 ) biases the armature toward a first position against the valve seat. An inlet fitting ( 106 ) and an outlet fitting ( 104 ) fluidly connect to the axial volume. The armature is movable by the magnetic field generated by the winding from the first position to a second position away from the valve seat, such that the valve can be selectively opened and closed.
