Toilet valve

1. A toilet bowl fill valve, comprising:

a valve body having a cavity, wherein the valve body attaches directly to a body of a toilet fill valve;

a valve inserted into the cavity of the valve body, a line contact being formed between the valve and the valve body, a first diameter of a first section of the valve corresponding to the line contact exceeding a second diameter of a second section of the valve, the first section and the second section are connected by a third section, wherein the third section has a slope that transitions from the first diameter to the second diameter, the first section having a first outer surface that is parallel to a second outer surface of the second section; and

a handle integrated with the valve, wherein the handle facilitates manual adjustment of the valve.

2. The toilet bowl fill valve of claim 1 , wherein the valve body forms a bowl fill valve outlet port.

3. The toilet bowl fill valve of claim 2 , wherein the bowl fill valve outlet port is configured to mate with a tube that extends to an overfill tube.

4. The toilet bowl fill valve of claim 1 , wherein the valve body forms a bowl fill valve inlet port.

5. The toilet bowl fill valve of claim 1 , wherein the valve and the handle are embodied as a single piece.

6. The toilet bowl fill valve of claim 1 , wherein the valve and the handle are embodied as multiple pieces.

7. The toilet bowl fill valve of claim 1 , wherein a seal is formed between the valve and the valve body.

8. The toilet bowl fill valve of claim 1 , wherein the valve body attaches directly to an extended portion of the body of the toilet fill valve, and wherein the extended portion of the body of the toilet fill valve is integrally molded with the body of the toilet fill valve.

9. The toilet bowl fill valve of claim 1 , wherein the third section comprises a plurality of diameters reducing at a constant rate between the first diameter and the second diameter.

10. The toilet bowl fill valve of claim 1 , wherein the valve body attaches directly to the toilet fill valve by being integrally molded with the body of the toilet fill valve.

11. A method, comprising:

inserting a valve into a cavity of a valve body for a toilet bowl fill valve;

attaching the valve body directly to a body of a toilet fill valve;

forming a line contact between the valve and the valve body, a first diameter of a first section of the valve corresponding to the line contact exceeding a second diameter of a second section of the valve, the first section and the second section are connected by a third section, wherein the third section has a slope that transitions from the first diameter to the second diameter, the first section having a first outer surface that is parallel to a second outer surface of the second section; and

adjusting the valve using a handle that is integrated with the valve.

12. The method of claim 11 , wherein the valve body forms a bowl fill valve outlet port.

13. The method of claim 12 , wherein the bowl fill valve outlet port is configured to mate with a tube that extends to an overfill tube.

14. The method of claim 11 , wherein the valve body forms a bowl fill valve inlet port.

15. The method of claim 11 , wherein the valve and the handle are embodied as a single piece.

16. The method of claim 11 , wherein attaching the valve body directly to the body of the toilet fill valve comprises attaching the valve body directly to an extended portion of the body of the toilet fill valve, wherein the extended portion of the body of the toilet fill valve is integrally molded with the extended portion of the body of the toilet fill valve.

17. The method of claim 11 , wherein at least a part of the third section is positioned above an outlet port and an inlet port of the valve.

18. The method of claim 11 , wherein attaching the valve body directly to the body of the toilet fill valve comprises integrally molding the valve body with the body of the toilet fill valve.
