Abstract: An illustrative example elevator system includes an elevator car and a valve assembly that selectively directs fluid flow to control movement of the elevator car. At least one sensor provides an indication of a current status of the elevator car, which includes at least a position of the elevator car or a speed of the elevator car. A processor receives the indication from the at least one sensor and adjusts operation of the valve assembly when the current status of the elevator car is different than a predetermined desired status.
