A valve having a valve body, a rotary valve member, a valve handle, and a selectively repositionable valve handle stop member. The valve body includes first and second openings into which the stop member may be installed. The openings are provided on opposite sides of the lower end of the valve handle such that, when the stop member is installed in the first opening, the valve handle is rotated in a first direction between a first orientation, which corresponds to the valve member being full open, and a second orientation, which corresponds to the valve member being full closed. Alternatively, when the stop member is installed in the second opening, the valve handle is rotated in a second, opposite direction to move the valve member from the full open to the full closed position. When no stop member is installed, the valve member is sequentially moved from the full closed position, to the full open position, and then to the full closed position as the valve handle traverses a 180° arc.

A valve, comprising:
A method for changing a direction of operation of a ball valve, said ball valve comprising a valve body, a valve member, and a valve handle, said valve member being rotatably disposed within said valve body and being rotatably movable between a full closed position and a full open position, said valve handle being secured to said valve member and being movable in a first direction and an opposite, second direction to move said valve handle from a first orientation, corresponding to the full open position of the valve member, and a second orientation, corresponding to the full closed position of said valve member, said valve body defining first and second threaded openings disposed on opposite sides of a lower end of said valve handle when said valve handle is in the first orientation, each of said openings being adapted to receive a stop member that is a threaded fastener and that limits rotation of said valve handle to one of said first and second directions, the method comprising the steps of:
