Product Introduction: This product is a high-performance electro-hydraulic servo valve under the D661 series of Moog. It has inherited the excellent performance of the D661 series and has been optimized and improved in some aspects. It adopts advanced servo jet pilot stage technology and closed-loop control strategy to realize high-precision flow and pressure control. It is equipped with integrated electronic devices, using SMD (surface mount technology) and 24V DC (direct current) power supply, which improves the stability and reliability of the product.
Technical Specifications: The maximum operating pressure is 350 bar. The rated flow rate is increased due to the large flow passage design inside the valve, and the maximum flow rate can reach 180 l/min. The response time is 10 ms to 42 ms. The resolution is less than 0.2%, and the hysteresis is less than 1.0%. The power supply voltage is 24V DC. The ambient temperature range is -20°C to 80°C.
Functional Features: It has high precision and responsiveness, and can realize high-precision control of the actuator. The integrated electronic device adopts SMD technology, which reduces the volume of the product and improves the anti-interference ability. It is equipped with a fault insurance function, which can ensure that the mechanical equipment is in a safe position when an unexpected power failure occurs. The spool is driven by a permanent magnet linear force motor, which has a large driving force and can maintain long-term and constant use.
Application Scenarios: It is widely used in the field of numerical control machine tools to realize high-precision control of the machine tool’s spindle speed and feed rate. In the aerospace field, it can be used in the hydraulic control system of aircraft and spacecraft to ensure the stable operation of flight control and attitude adjustment systems. It is applied in the field of industrial robots to realize precise control of the robot’s movement trajectory. In addition, it can also be used in the field of test equipment, such as flight simulators and vehicle test platforms, to improve the authenticity and accuracy of the test.
