The G761-3033B Servo Valve is specifically designed for the anti-fuel system of steam turbines to supply oil to the actuator of the safety regulation system, ensuring its normal operation. Due to the high pressure of the anti-fuel, small clearances in the hydraulic moving parts, and a servo valve clearance of 5 to 10 micrometers, it is essential to ensure that the oil particle size meets the specified SAE 2 or NAS 5 level before proceeding to the next stage of the debugging process.
Structure:
The G761 Series flow control servovalves are designed to provide high-performance control for electrohydraulic systems. The valve consists of a closed center, four-way sliding spool as its output stage, ensuring precise control and efficient operation. The pilot stage features a symmetrical double-nozzle and flapper, driven by a double air gap, dry torque motor. To provide accurate spool position feedback, a cantilever spring is used in the mechanical feedback system.
The G761-3033B Servo Valve stands out with its simple and rugged design, ensuring dependable and long-lasting performance. The design incorporates a carbide-tipped feedback wire, controlled by a carbide ball at its end, which is a mandatory requirement to ensure high accuracy, reliable operation, and extended service life.
