I have a problem with a hydraulic cylinder which is working on 3 way proportional valve as i have attached in the pic.. Some time the hydraulic cylinder doesn't go fully up or fully down. It moves up and down but doesnt reach the top and bottom limit switches. I see the pump is loaded the valves are set.It is working since 4 years. What could be the problem. Also can you guys explain the 3 way proportional valve in the diagram
