The invention discloses an electrically-controlled hydraulic steering valve, a system and a control method. The electrically-controlled hydraulic steering valve comprises an oil inlet unit, a steering unit and a locking unit. The oil inlet unit comprises a first valve body, and a first oil inlet P, a first oil outlet T and a load feedback oil port LS are formed in the first valve body; the steering joint comprises a second valve body, and a working oil port A and a working oil port B are formed in the second valve body; the locking coupler comprises a third valve body, and a working oil port Z and a working oil port S are formed in the third valve body. According to the electric control hydraulic conversion valve, the system and the control method, it is ensured that an existing load sensitive system can provide a constant pressure oil source for the neutral position locking oil cylinder, and an extra oil source is not needed.
