A solenoid assembly for use in connection with a housing and valve body is provided. The assembly includes a magnetic coil, a magnetic pole piece, an operating rod, a magnetic armature, and at least two bearings positioned between a portion of the magnetic pole piece and a portion of the operating rod. The operating rod is slidably disposed along the bearings. The magnetic armature is at least in part centered relative to the pole piece. Activation of the coil provides an attraction between the armature and the pole piece.

What is claimed is: 1. A solenoid assembly for use in connection with a housing and valve body, the assembly having a longitudinal axis and comprising: a magnetic coil; a magnetic pole piece, wherein a majority of the pole piece extends in a direction parallel to the longitudinal axis of the assembly and is positioned inside of the coil; an operating rod positioned within a portion of a cavity or aperture formed by the pole piece, wherein the operating rod and pole piece are concentric; a magnetic armature positioned about an end of the operating rod, the armature configured to interact directly with said housing; a first bearing positioned between a first portion of the magnetic pole piece and a first portion of the operating rod; and a second bearing positioned between a second portion of the magnetic pole piece and a second portion of the operating rod, wherein the first and second portions of the magnetic pole piece comprise a single, integral component; wherein the operating rod is slidably disposed along the first and second bearings, the armature is at least in part centered relative to the pole piece, and activation of the coil provides an attraction between the armature and the pole piece. 2. The assembly of claim 1, wherein the magnetic armature is positioned about an end of the operating rod that is more remote from said valve body. 3. The assembly of claim 1, wherein the magnetic armature is positioned about an end of the operating rod that is closer to said valve body. 4. The assembly of claim 1, including a spring element positioned about an end of the operating rod nearest the armature. 5. The assembly of claim 1, including a spring element positioned about an end of the operating rod that is more remote from the armature. 6. The assembly of claim 1, wherein the operating rod is comprised of non-magnetic material. 7. The assembly of claim 6, wherein the operating rod is comprised of stainless steel, aluminum, or brass. 8. The assembly of claim 1, wherein the operating rod is retained on-center by the pole piece. 9. The assembly of claim 1, wherein at least a portion of an associated flux travels from the pole piece, into and through the armature, and directly on to said housing. 10. The assembly of claim 1, wherein the activation of the coil attracts the armature to the pole piece. 11. The assembly of claim 1, wherein an associated dimensional tolerance stack-up for the assembly consists solely of the tolerances associated with the coil, pole piece, operating rod, and armature. 12. The assembly of claim 1, wherein the majority of the external surface of the operating rod is in operative contact with an internal surface of the pole piece. 13. The assembly of claim 1, wherein, when the coil is in a non-activated condition, the coil does not surround the armature. 14. The assembly of claim 1, wherein the magnetic armature is positioned externally at the end of the operating rod. 15. The assembly of claim 1, wherein at least a portion of the magnetic pole piece comprises the first and second bearings. 16. The assembly of claim 1, wherein at least a portion of the magnetic pole piece is configured to receive the first and second bearings. 17. A solenoid assembly for use in connection with a housing, the assembly having a longitudinal axis and comprising: a magnetic coil; a magnetic pole piece, wherein a majority of the pole piece extends in a direction parallel to the longitudinal axis of the assembly and is positioned inside the coil; an operating rod comprised of a non-magnetic material that is positioned within a portion of a cavity or aperture formed by the magnetic pole piece, wherein the operating rod and pole piece are concentric; a magnetic armature positioned about one end of the operating rod, the armature configured to interact directly with said housing; a first bearing positioned between a first portion of the magnetic pole piece and a first portion of the operating rod; and a second bearing positioned between a second portion of the magnetic pole piece and a second portion of the operating rod, wherein the first and second portions of the magnetic pole piece comprise a single, integral component; wherein the operating rod is slidably disposed on the first and second bearings; the armature is at least in part centered relative to the pole piece; activation of the coil provides an attraction between the armature and the pole piece; the operating rod is retained on-center by the at least two bearings; and the activation of the coil attracts the armature to the pole piece. 18. The assembly of claim 17, wherein, when the coil is in a non-activated condition, the coil does not surround the armature. 19. The assembly of claim 1, wherein the magnetic armature is positioned externally at the end of the operating rod. 20. A solenoid assembly for use in connection with a housing and valve body, the assembly having a longitudinal axis and comprising: a magnetic coil; a magnetic pole piece, wherein a majority of the pole piece extends in a direction parallel to the longitudinal axis of the assembly and is positioned inside of the coil; an operating rod positioned within at least a portion of a cavity or aperture formed by the pole piece, wherein the operating rod and pole piece are concentric; a magnetic armature positioned externally at an end of the operating rod; a first bearing positioned between a first portion of the magnetic pole piece and a first portion of the operating rod; and a second bearing positioned between a second portion of the magnetic pole piece and a second portion of the operating rod, wherein the first and second portions of the magnetic pole piece comprise a single, integral component; wherein the operating rod is slidably disposed along the first and second bearings and wherein at least a portion of the magnetic pole piece comprises the bearings or is configured to receive the bearings.
