Moog D661-5208/D6615208 Series Electro-Hydraulic Servo Valve
Moog D661-5208/D6615208 Series Electro-Hydraulic Servo Valve
Product Introduction: This product belongs to the D661 series of Moog servo valves, which is a high-performance electro-hydraulic servo control valve. Its working principle is based on electro-hydraulic conversion. It converts electrical signals into hydraulic signals, and then realizes the control of the actuator through the hydraulic control system. The product has been optimized and improved in terms of structure and performance, and can meet the needs of various complex industrial control occasions.
Technical Specifications: The maximum operating pressure is 350 bar. The rated flow rate is greatly 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.
Functional Features: It has high precision and responsiveness, and can realize high-precision processing and measurement, improving production efficiency and product quality. 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 ServoJet pilot stage is adopted, which is composed of a torque motor, a jet pipe and a receiver, improving the dynamic characteristics of the entire valve. The spool is driven by a permanent magnet linear force motor, which can flexibly drive the spool bidirectionally from the spring-centered position.
Application Scenarios: It is widely used in the field of numerical control machine tools to realize high-precision control of the machine tool spindle and feed system. In the aerospace field, it can be used in the hydraulic control system of aircraft to ensure the stable operation of flight control systems and landing gear. It is also applied in the petrochemical industry, such as the control system of oil refining equipment and chemical reactors. In addition, it can be used in the power industry, such as the control system of power generation equipment.
