1. A valve for limiting excess flow, said valve comprising: a one-piece body defining a center axis, said one-piece body having;a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein said legs extend in an axial direction from said seat to attach to said diaphragm. 2. The valve of claim 1 wherein said legs attach to a periphery of said diaphragm. 3. The valve of claim 2 wherein said legs have a curved portion extending at an angle of about 90° therefrom that attaches to said periphery of said diaphragm if said limit is not exceeded. 4. The valve of claim 1 wherein said legs flex above said diaphragm, if said limit is exceeded. 5. The valve of claim 1 wherein said legs flex radially inwardly if said limit is exceeded. 6. The valve of claim 1 wherein said seat comprises a base defining an inner diameter and an upstream portion extending from said base and having an outer diameter that is greater than the inner diameter, and wherein the legs extend axially from the upstream portion to the diaphragm. 7. A valve for limiting excess flow, said valve comprising: a one-piece body, said one-piece body having;a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs attach to a periphery of said diaphragm and flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein said legs have a curved portion extending at an angle of about 180° therefrom that attaches to said periphery of said diaphragm if said limit is exceeded. 8. A valve for excess flow, said valve comprising: a one-piece body, said one-piece body having;a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein a top portion of each leg in a first position in which said limit is not exceeded, is in a second position adjacent a bottom portion of said leg if said limit is exceeded. 9. The valve of claim 8 wherein said bottom portion flexes radially outwardly if said limit is exceeded. 10. The valve of claim 8 wherein said top portion flexes radially inwardly if said limit is exceeded. 11. The valve of claim 8 wherein said top portion and said bottom portion are parallel to each other if said limit is exceeded. 12. A valve for excess flow, said valve comprising; a one-piece body, said one-piece body having;a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein a central portion of said legs flexes radially inwardly if said limit is exceeded. 13. A valve for limiting excess flow, said valve comprising: a one-piece body, said one-piece body having;a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein the legs flex radially inwardly between said diaphragm and said seat if said limit is exceeded. 14. A valve for limiting excess flow, said valve comprising: a one-piece body, said one-piece body having;a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein said legs attach to an inner portion of said seat and a downstream portion of said diaphragm. 15. A valve for limiting excess flow, said valve comprising: a one-piece body, said one-piece body having:a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein said seat has an inner shoulder for seating said diaphragm there against. 16. The valve of claim 15 wherein said diaphragm has a flange that seats within an inner diameter of said seat. 17. A valve for limiting excess flow, said valve comprising: a one-piece body, said one-piece body having;a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein said legs double over if said limit is exceeded. 18. A valve for limiting excess flow, said valve comprising: a one-piece body said one-piece body having;a seat comprising a base defining an inner diameter and an upstream portion extending from said base and having an outer diameter that is greater than the inner diameter,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein the legs extend axially from the upstream portion to the diaphragm, and wherein said base includes an internal shoulder with a tapered portion, and wherein said diaphragm includes an angled shoulder formed around an outer edge of said diaphragm, said angled shoulder seating against said tapered portion when said limit is exceeded. 19. A valve for limiting excess flow, said valve comprising: a one-piece body, said one-piece body having;a seat,a diaphragm, anda plurality of flexible legs attaching said seat to said diaphragm and spacing said seat from said diaphragm, wherein said legs flex to seat said diaphragm within said seat if excess flow exceeds a limit, and wherein said seat, said diaphragm, and said legs are formed from a common material. 20. A valve for limiting excess flow, said valve comprising: a one-piece body defining a center axis, said one-piece body including a seat,a valve plate, anda plurality of flexible legs extending in a generally axial direction from said seat to said valve plate and spacing said valve plate from said seat in a first flow condition where flow is below a limit, and wherein said legs flex to seat said valve plate against said seat in a second flow condition where flow exceeds said limit. 21. The valve of claim 20 wherein said seat comprises a cylindrical base defining an internal orifice, said cylindrical base extending to a top wall, and wherein said legs extend directly between said top wall and an outer peripheral edge of said valve plate. 22. The valve of claim 21 wherein an upper portion of said legs is attached to said outer peripheral edge and a lower portion of said legs is attached to said top wall, and wherein said upper portions are located radially inward of said lower portions in said second flow condition. 23. The valve of claim 20 wherein an upper portion of said legs is attached to a bottom of said valve plate and a lower portion of said legs is attached to a radially inner surface of said seat, and wherein a center portion of said legs extends radially inwardly when in said second flow condition. 24.
