| description | The open-loop proportional reversing valve comprises a pilot valve element and a main valve element, and the two ends of the pilot valve element are connected with manual operation screw rods through pilot valve element reset springs correspondingly; the two ends of the main valve element are connected with a first control cavity and a second control cavity through throttlers, and main valve element reset springs are installed in the first control cavity and the second control cavity. The main valve element is located in the main valve sleeve reversing cavity, a first reversing opening, a second reversing opening and a first oil inlet are formed in the pilot valve reversing cavity, the first reversing opening is connected with the first control cavity through a first channel, and the second reversing opening is connected with the second control cavity through a second channel; a third reversing port, a fourth reversing port and a second oil inlet are formed in a reversing cavity of the main valve sleeve; and |
