Abstract
A ball valve includes a valve housing that has a main passage defined therein and a valve assembly that includes a valve body, which is movable within the main passage between open and closed positions, and a valve stem that fixedly engages the valve body. A handle is disposed on the valve housing that is connected to the valve stem and is operable to rotate the valve body between the open and closed positions via the valve stem. A switch is disposed within the housing, which operatively engages the valve assembly and is configured to transmit a signal to an operator's station regarding the position of the valve body.
