Electromagnetic combined reversing valve

The utility model discloses an electromagnetic combined reversing valve, and belongs to the technical field of reversing valves. The four normally-closed electromagnetic valves are used for independently controlling the communication relation between the oil ports, pilot-operated cartridge valves are selected as the normally-closed electromagnetic valves, the opening pressure is high, and the flow is large; the pressure sensor is monitored through a control program, the power-on advance of the normally-closed electromagnetic valve is controlled, and the reversing response speed is increased; in addition, when the electromagnetic combination reversing valve does not work, the oil port P and the oil port T are communicated, and the load of an engine or a motor driving the oil port P is reduced. According to the electromagnetic combined reversing valve, the design of an electromagnetic valve and the configuration of a flow channel are optimized, and the response speed of the reversing valve is increased; by the
