A valve assembly is provided. The valve assembly includes a valve housing having an internal generally cup-shaped bore, a valve control cartridge inserted into the bore and having a rotatable control stem extending upwardly therefrom, and a bonnet nut threaded to an internal wall of the valve housing. The bonnet nut has a through channel that surrounds the control stem, and means are provided along the through channel to control a level of resistance to rotation of stem.

1. A valve assembly, comprising: a valve housing having an axially extending bore;a valve control cartridge received in the bore, the valve control cartridge having a valve cartridge housing and a valve stem extending axially therefrom and rotatable relative to the valve cartridge housing;an o-ring positioned between the valve cartridge housing and the valve stem to seal an interface therebetween;a bonnet nut having a through-bore, the bonnet nut coupled to the valve housing such that the control stem extends through the through-bore; andan interface between the valve stem and the through-bore, the interface configured to provide a desired rotational feel of the valve stem. 2. The valve assembly of claim 1, wherein the desired rotational feel comprises a level of rotational resistance at the interface. 3. The valve assembly of claim 1, wherein the bonnet nut is threadably coupled to the valve housing. 4. The valve assembly of claim 3, wherein the valve housing comprises internal threads and the bonnet nut comprises external threads, the external threads of the bonnet nut engaging the internal threads of the valve housing. 5. The valve assembly of claim 1, wherein the bonnet nut comprises a counterbore axially aligned with the through bore, the valve cartridge housing received in the counterbore. 6. The valve assembly of claim 1, wherein the bonnet nut couples to the valve housing with a bayonet mounting. 7. The valve assembly of claim 1, wherein the interface comprises flexible fingers. 8. The valve assembly of claim 7, wherein the flexible fingers are formed of an elastomeric material. 9. The valve assembly of claim 1, wherein the interface comprises a viscous lubricant. 10. The valve assembly of claim 9, wherein the bonnet nut defines a pocket adjacent to the through-bore, the pocket at least partially filled with the viscous lubricant. 11. The valve assembly of claim 1, wherein the interface comprises a set of bearings. 12. The valve assembly of claim 1, wherein the interface comprises a glass-filled polymeric sleeve. 13. A valve assembly, comprising: a valve housing having an axially extending bore;a valve control cartridge received in the bore, the valve control cartridge having a valve cartridge housing and a rotatable control stem extending axially therefrom;a bonnet nut having a through-bore, the through-bore having an inner surface, and the bonnet nut coupled to the valve housing such that the control stem extends through the through-bore in contact with the inner surface;wherein the valve cartridge housing is rotationally fixed relative to the valve housing;wherein an interface between the control stem and the inner surface of the through-bore is configured to provide a controlled level of resistance to a rotation of the control stem relative to the valve cartridge housing. 14. The valve assembly of claim 13, wherein the bonnet nut is threaded to an internal wall of the valve housing. 15. The valve assembly of claim 13, wherein the bonnet nut is at least partially formed of a glass-filled polymer such that the inner surface comprises a polymeric surface. 16. The valve assembly of claim 13, wherein a shape of the through-bore includes a pocket, the pocket at least partially filled with a lubricant. 17. The valve assembly of claim 16, wherein the lubricant comprises a viscous lubricant. 18. The valve assembly of claim 13, wherein the bonnet nut couples to the valve housing with a bayonet mounting.
