EMG Servo Valve Type SV2-16
A pilot valve SV1-10, which is suitable for pressure control, is placed on a valve block. Together with the main valve, which contains a piston slide valve, an inductive position transducer as well as a control amplifier, a closed control system is realized. Via the internal lines of the pilot valve the piston slide valve is pushed with pressure against the spring force. By this the hydraulic fluid is led to the operating lines A or B. The inductive position transducer meanwhile monitors the position of the main control piston. The volume flow is determined by the position of the piston slide valve and is proportional to the input current of the control amplifier. The piston is held in the middle position by two pressure springs, e. g. in case of power breakdown.
