Product Introduction: This is a high-performance servo valve from Moog’s D651 series, designed for precision control in medium-flow hydraulic systems. It combines a pilot-operated design with electronic feedback to convert electrical signals into hydraulic flow, ensuring accurate actuator positioning. The valve is engineered for reliability, with components tested to withstand millions of cycles in industrial applications.
Technical Specifications: The maximum operating pressure is 350 bar (5,000 psi). The rated flow rate is 20–100 l/min (5.3–26.4 gpm) at a pressure drop of 35 bar (500 psi). It operates on 24 VDC (18–32 VDC) and accepts ±10 V or 4–20 mA input signals. The step response time is 10–20 ms, with a frequency response of 40–80 Hz for dynamic control.
Functional Features: Electronic feedback via a displacement sensor ensures closed-loop control, with resolution <0.1% for precise adjustments. The pilot stage uses a nozzle-flapper design for high sensitivity, while the main spool features hard chrome plating for wear resistance. The valve includes a built-in filter to protect critical components from contamination, extending service life. It offers multiple fail-safe options, allowing customization for specific safety requirements.
Application Scenarios: Ideal for CNC machine tools, controlling axis movements for high-precision machining. In packaging machinery, it regulates conveyor speed and sealing pressure for consistent product packaging. It also controls hydraulic actuators in renewable energy systems, such as solar tracker positioning, to maximize energy capture.
