Disclosed is an electric-control multimode steering valve. The steering valve comprises: a flow distributing and collecting valve (Y), a first electromagnetic exchange valve (Y1), and a second electromagnetic exchange valve (Y2). A valve body comprises four groups of paired valve oil ports. First oil ports of the first electromagnetic exchange valve (Y1) and the second electromagnetic exchange valve (Y2) are respectively in communication with a first group of valve oil ports (PR, PL) of the valve body. Second oil ports of the first electromagnetic exchange valve (Y1) and the second electromagnetic exchange valve (Y2) are respectively in communication with a second group of valve oil ports (A1, B1) of the valve body. A third oil port of the first electromagnetic exchange valve (Y1) is in communication with a flow collecting port of the flow distributing and collecting valve (Y). A first flow distributing port of the flow distributing and collecting valve (Y) and a third oil port of the second electromagnetic exchange valve (Y2) are respectively in communication with a third group of valve oil ports (A2, B2) of the valve body. A second flow distributing port of the flow distributing and collecting valve (Y) and the third oil port of the second exchange valve (Y2) are respectively in communication with a fourth group of valve oil ports (A3, B3) of the valve body. Further disclosed are a steering hydraulic control system and a wheel type crane. The steering valve can implement multimode steering of engineering vehicles, and the working is reliable and the cost is low.
