Product Introduction: As a member of Moog’s servo valve product line, the D644-303 servo valve is designed to achieve precise control of hydraulic systems. It converts electrical signals into hydraulic signals to control the movement of actuators, and is widely used in industrial fields requiring high-precision control.
Technical Specifications: Specific parameters need to be referred to the official technical manual, and it is generally similar to products of the same series. The maximum working pressure can reach 350 bar (5000 psi), and the rated flow rate varies according to different working conditions. The supply voltage is usually 24 VDC (18 to 32 VDC), and the rated signal options include +/- 10 V, +/- 10 mA, 4 – 20 mA.
Functional Characteristics: It has the characteristics of high control precision and fast dynamic response, which can quickly and accurately respond to input signals and realize precise control of flow and pressure. The integrated electronic amplifier realizes closed-loop control of the spool position, improving the stability and reliability of the system. It also has good anti-pollution performance, which can work stably in harsh working environments.
Application Scenarios: It is suitable for various industrial fields, such as the control system of injection molding machines, ensuring the precision and stability of the injection molding process; in the field of metal forming, it is used to control the movement of presses and other equipment; it is also applied in the test equipment of aerospace and automotive industries to provide precise hydraulic control for product testing.
