[0002] The reversing valve is the most widely used type of valve in the hydraulic system, with the most complex varieties and names. It is a valve that realizes the hydraulic oil cut-off and reversing, as well as pressure unloading and sequential action control; it is a directional control valve that relies on the relative movement of the valve stem and the valve body. The electromagnetic reversing valve uses the suction force generated by the armature being energized and sucked to push the valve stem to change the working position of the valve, and change the connection relationship between the various valve ports on the valve body to achieve the connection and disconnection of the liquid circuit and control the flow direction of the liquid. Generally speaking, in the hydraulic circuit, a reversing valve is required to control the actuators that do not act at the same time. In order to make the hydraulic system run smoothly, the reversing valve is an indispensable part of the hydraulic system.
