<p>A two stage pressure control valve has a poppet movable toward and away from a valve seat to vary the cross-sectional area of a passageway from an inlet to an outlet. The position of the poppet is dependent in part on the difference in pressure between a fluid pressure at the inlet which exerts an force on the poppet in one axial direction and a control pressure which is produced by a fluid flow from the inlet in a chamber downstream from the inlet and which exerts a force on the poppet in the opposite axial direction. The control pressure is controlled by an electromagnetic coil which can be variably energized to move an armature so as to vary a variable restriction downstream from the control pressure so as to vary the control pressure. A tube extends through and forms an axial sliding seal with the poppet and communicates a flow of fluid from the inlet to the variable restriction and the chamber is positioned adjacent to an exterior surface of the tube. An orifice through a wall of the tube communicates a lumen of the tube with the chamber.</p>
