An emission control valve for an internal combustion engine having a body having an inlet port, an outlet port, a through-bore, and a seat area. A non-flow through member disposed within the through-bore, the non-flow-through member including a head connected to a stem with a free distal end, the stem having a cross-sectional area disposed within the through-bore and exposed to pressure of an operative medium at the outlet port when the head is blocking operative communication between the inlet port and each of the outlet port and the through-bore such that pressure at the outlet port acts on the cross-sectional area of the stem disposed within the through-bore in a direction opposite the direction in which the pressure at the outlet port acts on the head. An armature that moves the non-flow through member to allow operative communication between the inlet port to the outlet port having a stator structure having at least one two-part pole piece including a central hub part and an outer rim part that are joined together. A locator proximate the free distal end of the stem and a locator that bears against the armature at a single load operative connection. |
