Abstract: A valve assembly for a process fluid is disclosed that includes an integrated controller configured to control an on-off valve actuator based on signals from a sensor that indicates a measured parameter of the process fluid. The integrated controller is further configured to: (i) in response to receiving a first signal corresponding to an open-position valve command signal, control the on-off valve actuator to move the valve element from a starting position to a first partially-open position, (ii) evaluate a first criteria condition for further actuation of the valve element, (iii) in response to the first criteria condition being satisfied, control the on-off valve actuator to move the valve element to a second partially-open position, and (iv) in response to receiving a second signal corresponding to a closed-position valve command signal, control the on-off valve actuator to move the valve element to the closed position.
