Abstract
A valve assembly comprises a rotatable valve, an electrically operated actuator, and an overstroke device. The actuator comprises a component configured to move in a direction to an actuator position so as to cause corresponding rotation of the valve to a valve position in response to electrical operation of the actuator. The overstroke device is configured to enable the component to move in the direction beyond the actuator position to an overstroke position while the valve remains in the valve position in response to electrical operation of the actuator.
