An apparatus and method for controlling fluid flow is disclosed. An electromagnetic actuator may include a stator having an inner pole member and an outer pole member. The outer pole member may have a fluid passageway therein for transmitting fluid through the outer pole member. The actuator may further include a coil disposed around the inner pole member and arranged between the inner pole member and the outer pole member. The actuator may also include an armature moveable under the influence of a magnetic field generated by the stator and coil and operable to affect transmission of the fluid through the fluid passageway.
