Descrição: This patent describes an electrohydraulic valve control system. It comprises a valve including a manifold having openings for connection to a source of hydraulic fluid and to a load, a valve element variably positionable in the manifold for controlling flow of fluid among the openings, a stator including electronic coil means mounted on the manifold for receiving valve control signals, an armature coupled to the valve element and responsive to the stator coil means for variably positioning the valve element within the manifold, and valve driven means for supplying the valve control signals to the stator coil means. It also comprises: a solid state switch having power electrodes for selectively applying electrical power to the stator coil means and having a control electrode, means for supplying a switch control signal, switch circuit means responsive to the switch control signal and coupled to the control electrode for setting the switch circuit means and applying power to the coil means responsive to the switch control signal, and means responsive to current through the coil means for resetting the switch circuit means and terminating application of electrical power to the coil means independently of the switch control signal.
