Solenoid control valve for a hydraulic control unit

A control valve for controlling fluid flow in a hydraulic control unit of, for example, a vehicular brake system includes a tube. A flux cap is pressed onto one end of the tube. A flux ring pole is pressed onto an opposite end of the tube. An armature is slidably received in the tube. A coil subassembly is provided about the tube, flux cap, and flux ring pole. A valve seat receives the flux ring pole. The valve seat is mounted in a bore of a hydraulic control unit of a vehicular brake system. Alternate embodiments using a "three piece" armature sleeve having a center non-magnetic section are also disclosed.
