摘要： The invention relates to an electrohydraulic valve system comprising a feeding duct (P), a working duct (A), and a discharge duct (T), a first and a second valve mechanism (20, 30), each of which is provided with a valve piston (3.1), a control device, and a magnetic regulating device for impinging the valve piston (3.1, 3.2) with a controlled actuating force. The first and the second valve mechanism (20, 30) are placed parallel to each other. The first valve mechanism or the second valve mechanism is active and performs the function of the electrohydraulic valve system while the other valve mechanism is passive during operation. The control device of the active valve mechanism activates the passive valve mechanism and deactivates itself when said control device recognizes a fault while the control device of the passive valve mechanism activates itself and deactivates the active valve mechanism when the control device of the passive valve mechanism recognizes a fault. Deactivation of a valve mechanism comprises moving the valve piston of said valve mechanism to the neutral hydraulic position by means of an apparatus that is separate from the magnetic regulating device.

摘要： The invention relates to an electromechanical drive for actuating valves, especially in steam turbines including an electromotor, a linear unit, a clutch and an electronic control unit. The linear unit includes a piston rod which is guided in a power-transmission thread of a screw nut, and is arranged, at least in sections, as a spindle and is displaceable along its longitudinal axis for actuating the valve in the screw nut with the power-transmission thread. The clutch is arranged for transmitting a rotational movement of the motor axis of the electromotor onto the piston rod. The electronic control unit is set up to control the speed and/or rotor position of the motor axis of the electromotor depending on a control signal and an output signal of a position pick-up of the position of the piston rod in the screw nut with power-transmission thread, and/or to control the engagement and/or disengagement of the clutch depending on the control signal.

摘要： An electrohydraulic valve assembly having an inflow channel, a working channel and an outflow channel, including first and second valves each having a magnetic regulating device for applying a regulated activation force to the respective valve. The valves are arranged in parallel so that either can provide the hydraulic connection between the inflow, working and outflow channels. In the case of error detection, the active valve is deactivated and the until then passive valve is activated and vice-versa. The deactivating of a valve device moves the valve piston to a hydraulic neutral position by means of a second stage.
