Product Overview
The MOOG G761-3005B / 563JOGM4VPL is a high-performance two-stage electrohydraulic servo valve manufactured by MOOG, the global benchmark in precision motion control. This valve utilizes a torque-motor driven, dual-nozzle pilot stage that hydraulically positions a precision-ground spool within the second stage, delivering infinitely variable flow control proportional to the electrical input signal. Engineered for closed-loop position, velocity, and force control architectures, the G761 series servo valve serves as the critical control element in high-dynamic industrial and aerospace-grade hydraulic systems where micron-level positioning accuracy, fast response, and long-term null stability are mandatory.

Engineering Features & Advantages
- Precision Performance: The dual-nozzle flapper pilot stage provides extremely high hydraulic gain, enabling spool positioning resolution in the sub-micron range and precise, repeatable flow metering proportional to the command signal.
- Fast Dynamic Response: Low-inertia torque motor and optimized pilot stage deliver high frequency response (typically 100–200 Hz at 90° phase lag), essential for closed-loop servo control of high-acceleration actuators.
- Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original MOOG standards, allowing straightforward retrofit into existing hydraulic systems without rework.
Typical Industrial Applications
Engineered for closed-loop position, velocity, and force control architectures, the G761 series servo valve serves as the critical control element in high-dynamic industrial and aerospace-grade hydraulic systems where micron-level positioning accuracy, fast response, and long-term null stability are mandatory.
