More Information
Summary:The utility model discloses a hydraulic program control change valve. The hydraulic program control change valve is composed of a program controller and a change valve. NOR, NON, and 'AND'functional elements and memory functional elements are arranged inside the program controller. An upper valve core and a lower valve core are arranged inside the change valve. Four programs can be given by the program controller. The output oil path of the hydraulic program control change valve is respectively communicated with the oil control openings of two valve cores of a double-core change valve on the lower surface of the hydraulic program control change valve. The hydraulic program control change valve of the utility model can directly control power components to realize program action. The existing hydraulic system which must adopt an intermediate control link relay or a microcomputer for control is not needed to be used. The utility model has the advantages of simple structure, high reliability, low cost, energy saving, and convenient manufacture and maintenance.
