A method for controlling the flow of fluid includes providing a valve assembly including a ball valve having a spherical disk, a substantially circular handle connected to the spherical disk ball valve that is configured to move between a first position and a second position relative to the ball valve, and a biasing member configured to bias the substantially circular handle towards the ball valve. In order to control the flow of the fluid, the substantially spherical handle may be moved from the first position to the second position. |
