An apparatus for exercising an emergency shutoff valve of a steam turbine and methods for operating the same are disclosed herein. A cover of the valve exerciser mounts on top of an emergency shutoff valve body and through a stroker bolt threadingly engaged with the shutoff valve lever arm, the valve stem is moved within a passageway of the cover a small amount so that the aperture between the steam inlet and outlet is not blocked, thereby permitting normal operation of the steam valve while the valve stem is exercised.
