MOOG G761-3004B5 H38JOGM5VPH Servovalve

The functional features of MOOG G761-3004B servo valve mainly include the following aspects:1. Design of high-performance two-stage valveG761-3004B is a high-performance two-stage electro-hydraulic servo valve with the characteristics of simple structure, durability, reliable operation and long service life.2. Cross slide valve output stageThe output stage of the servo valve adopts cross slide valve design, and the position of the valve core is mechanically fed back by the cantilever spring rod, which ensures the precise control and stability of the valve.3. High dynamic responseG761-3004B servo valve has high dynamic response characteristics, and its linear torque motor has high undamped natural frequency, which makes the dynamic response of servo valve independent of system pressure, thus improving the overall response speed of the system.4. Closed-loop control feedbackThe servo valve integrates a lossless linear displacement sensor (LVDT) and realizes the closed-loop control feedback of the valve position. This design improves the control accuracy and stability of the system, so that the actual displacement of the valve is proportional to the command electrical signal.5. Optional high response kitG761-3004B provides standard response or optional high response suite to meet the needs of different application scenarios. Especially when fast response is needed, the high response suite can significantly improve the performance of the system.6. Suitable for multi-valve control systemBecause there is no internal leakage in the pilot stage, the power consumption of G761-3004B servo valve is low, which is especially suitable for multi-valve control system. This helps to reduce the overall energy consumption of the system and improve the energy utilization efficiency.7. Meet ISO standardsThe installation dimension of G761-3004B servo valve conforms to ISO4401 standard (the external control oil port does not conform to ISO4401 standard), which makes the servo valve more convenient and reliable when it is integrated with other equipment or systems.8. High resolution and low hysteresisThe servo valve has the characteristics of high resolution and low hysteresis, which is helpful to improve the control accuracy and repeatability of the system. These characteristics are particularly important in situations where precise control is needed.9. Emergency failure protectionIn case of power failure, cable damage or emergency stop, the valve core of G761-3004B servo valve will automatically return to the middle position corresponding to the middle spring to keep the load safe. This design improves the security and reliability of the system.10. Easy to maintain and debugThe design of G761-3004B servo valve takes into account the requirement of easy maintenance and debugging. For example, the external zero offset adjustment allows technicians to manually adjust the servo valve zero offset to adapt to the working conditions of machinery and equipment. In addition, the field replaceable pilot oil filter also makes preventive maintenance more convenient and faster.To sum up, MOOG G761-3004B servo valve has been widely used in aviation, aerospace, ships, metallurgy, chemical industry and other industries because of its high performance, high dynamic response, closed-loop control feedback, optional high response suite, suitability for multi-valve control system, ISO standard, high resolution and low hysteresis, emergency failure protection and easy maintenance and debugging.
