摘要：A method of operating a control valve assembly for a hydraulic system includesdetecting the current operation of a first position sensor and a second position sensor todetermine if at least one of the first position sensor and the second position sensor isinoperable. A pressure of the fluid at a first work port and a second work port ismeasured, and one of a first valve and a second valve is actuated when one of the firstposition sensor and the second position sensor is determined to be inoperable. The firstvalve is actuated based upon the fluid pressure measured at the second work port toadjust the flow of the fluid through the first work port. The second valve is actuatedbased upon the fluid pressure measured at the first work port to adjust the flow of thefluid through the second work port.
