    Abstract: A valve including a body having a first port, a second port, and a through-bore. A valve member disposed within the through-bore. The valve member having a head and stem configuration exposed to the first port so that the pressure of an operative medium in the first port acts in one direction on the stem and in an opposite direction on the head when the head blocks operative communication between the first and the second ports, the valve stem having a free distal end. A spring that biases the valve member so that the head blocks operative communication between the first and the second ports. An electromagnetic actuator having an armature that moves the valve member to allow operative communication between the first and second ports. A locator that is proximate the free distal end of the stem and that bears against the armature at a single load operative connection.
