Fluid valves having adjustable sealing characteristics are described. An example fluid valve includes a valve body (202) having a flow aperture to enable the flow of fluid therethrough. Additionally, the fluid valve includes a seal surrounding the flow aperture and a sealing member having a shaft extending therefrom. The sealing member (208) is movable relative to the seal and the flow aperture to control the flow of fluid through the flow aperture. Further, the fluid valve includes a support body (218) movably coupled to the valve body and having a passage to receive the shaft. The support body holds the shaft (212) and the sealing member to enable rotation of the shaft and the sealing member relative to the valve body and the seal, and at least one of the support body or the valve body includes at least one elongated opening to enable movement of the support body relative to the valve body to change an amount of engagement between the sealing member and the seal when the fluid valve is in a closed position. |
