Moog D651-470 Hydraulic Servo Valve
- Product Introduction: It is a hydraulic servo valve with excellent performance produced by Moog. It is an important component in the hydraulic servo system. It can convert the electrical control signal into hydraulic energy to drive the executive component to move, and realize the precise control of the position, speed, and force of the executive component.
- Technical Specifications: The maximum working pressure is 35.0 MPa. The flow range is 30 – 1500 l/min when the valve pressure drop is 1.0 MPa. The resolution is less than 0.2%, and the hysteresis is less than 1.0%. The response time is 10 – 42 ms.
Detailed content
- Functional Features: It has the advantages of fast dynamic response, high control precision, and good stability. It can quickly adjust the output flow and pressure according to the input signal, so that the executive component can quickly reach the specified position or speed. Its high control precision can ensure the accuracy of the system’s control of the executive component. At the same time, it has strong anti-interference ability and can work stably in a complex working environment.
- Application Scenarios: It is widely used in the hydraulic servo systems of metallurgy, mining, engineering machinery, and other fields. For example, in the rolling process of metallurgical enterprises, it can control the pressure and speed of the rolling mill to ensure the quality of the rolled products; in the mining process of mines, it can control the action of mining machinery to improve mining efficiency; in engineering machinery such as excavators and loaders, it can control the movement of the working device to improve the operation precision and efficiency of the machinery.
