Fluid flow control members for use with valves are described herein. An example fluid flow control member for use with a valve includes a body having a seat to control a fluid flow through the valve. The body defines a seating surface, an aperture to receive a stem of the valve and a plurality of substantially flat surfaces to enable gripping an exterior surface of the body.

1. A fluid flow control member for use with a valve, comprising: a body having a seat to control a fluid flow through a valve, wherein the body defines: a seating surface;an aperture to receive a stem of the valve; anda plurality of substantially flat surfaces to enable gripping an exterior surface
1. A fluid flow control member for use with a valve, comprising: a body having a seat to control a fluid flow through a valve, wherein the body defines: a seating surface;an aperture to receive a stem of the valve; anda plurality of substantially flat surfaces to enable gripping an exterior surface of the body, wherein the exterior surface defines a conically shaped portion. 2. The fluid flow control member as defined in claim 1, wherein the fluid flow control member is a poppet for use with the valve. 3. The fluid flow control member as defined in claim 1, wherein the plurality of substantially flat surfaces comprise step-shaped surfaces. 4. The fluid flow control member as defined in claim 1, further comprising at least one fluid flow channel through the body to fluidly couple a chamber of the valve to another chamber. 5. The fluid flow control member as defined in claim 4, wherein the at least one fluid flow channel has an opening positioned adjacent the aperture and the seat. 6. The fluid flow control member as defined in claim 4, wherein the at least one fluid flow channel is to increase a fluid flow rate between the other chamber and the chamber of the valve. 7. The fluid flow control member as defined in claim 4, wherein the at least one fluid flow channel is to increase a rate at which a pressure of the other chamber equalizes with a pressure of the chamber of the valve. 8. The fluid flow control member as defined in claim 1, wherein the stem comprises a cylindrical body. 9. The fluid flow control member as defined in claim 1, wherein a size of the aperture corresponds to a size of the stem to guide the stem relative to the body. 10. The fluid flow control member as defined in claim 1, wherein the flat surfaces are substantially parallel to one another. 11. A fluid flow control member for use with a valve, comprising: a body having a seat to control a fluid flow through a valve, wherein the body defines: a seating surface;an aperture to receive a stem of the valve; anda plurality of substantially flat surfaces to enable gripping an exterior surface of the body, wherein the stem comprises a surface to substantially prevent fluid flow through the body when the seating surface sealingly engages the valve and a plug of the valve is in a fully open position. 12. A fluid flow control member for use with a valve, comprising: a body having a seat to control a fluid flow through a valve, wherein the body defines: a seating surface;an aperture to receive a stem of the valve;a plurality of substantially flat surfaces to enable gripping an exterior surface of the body; andfluid flow channels through the body to fluidly couple a chamber of the valve to another chamber, the fluid flow channels having separate openings adjacent the seating surface. 13. A fluid flow control member for use with a valve, comprising: a body having a seat to control a fluid flow through the valve, wherein the body defines: a seating surface;an aperture to receive a stem of the valve; anda plurality of substantially flat surfaces to enable gripping an exterior surface of the body; anda sliding member having an exterior surface to slidably and sealingly engage a bore defined by the body, the aperture is different than the bore. 14. The fluid flow control member as defined in claim 13, wherein the bore is coaxially aligned with the aperture and surrounded by the seat. 15. The fluid flow control member as defined in claim 13, further comprising a plate coupled to the body to position the sliding member within the bore. 16. The fluid flow control member as defined in claim 13, wherein the sliding member is to move relative to the bore in response to being engaged by the surface of the spring seat. 17. A fluid flow control member for use with a valve, comprising: a body having a seat to control a fluid flow through the valve, wherein the body defines: a seating surface;an aperture to receive a stem of the valve; anda plurality of substantially flat surfaces to enable gripping an exterior surface of the body;a sliding member having an exterior surface to slidably and sealingly engage a bore defined by the body;a plate coupled to the body to position the sliding member within the bore; anda biasing element positioned within the bore to urge the sliding member away from the body. 18. A fluid flow control member for use with a valve, comprising: a body having a seat to control a fluid flow through the valve, wherein the body defines: a seating surface;an aperture to receive a stem of the valve; anda plurality of substantially flat surfaces to enable gripping an exterior surface of the body; anda sliding member having an exterior surface to slidably and sealingly engage a bore defined by the body, wherein the sliding member has a surface to be engaged by a surface of a spring seat coupled to the stem to control a fluid flow between another chamber and a chamber of the valve. 19. A fluid flow control member for use with a valve, comprising: a body having a seat to control a fluid flow through the valve, wherein the body defines:a seating surface;an aperture to receive a stem of the valve; anda plurality of substantially flat surfaces to enable gripping an exterior surface of the body, wherein the flat surfaces comprise first surfaces being substantially parallel to one another and second surfaces being substantially co-planer to one another, respective first and second surfaces defining opposing steps.
