A method for switching an electromagnetically actuable hydraulic valve including a switching element and an electromagnet having a coil and an armature connected to the switching element for joint movement. When a current is applied to the coil, the armature moves together with the switching element from an initial position to an end position for a switching operation. The method includes the following steps: applying a switching voltage to the coil of the electromagnet to initiate the switching operation; capturing the current curve over time; reaching-detection of the end position of the switching element; determining a holding current taking into account the reaching-detection of the end position of the switching element and the captured current curve; and reducing the current applied to the coil to the determined holding current. A hydraulic valve with a control unit which performs the disclosed method is also disclosed.
A method for switching an electromagnetically actuated hydraulic valve, wherein the hydraulic valve comprises a switching element and an electromagnet having a coil and an armature, the armature being connected to the switching element for joint movement, and wherein the coil, when energized with a current, moves the armature together with the switching element from an initial position to an end position for a switching operation, the method being performed by a control unit and comprising the following steps:
