Product Overview
The MOOG G761-3003B / H19JOGM4VPL is a high-performance two-stage electrohydraulic servo valve manufactured by MOOG, the global benchmark in precision motion control. This valve operates on a nozzle-flapper pilot stage that hydraulically positions a robust spool within the second stage, delivering infinitely variable, bidirectional flow control proportional to the electrical input current. As a critical control element in closed-loop industrial systems, the G761 series servo valve translates low-power electrical command signals into precise hydraulic flow and pressure outputs, enabling exceptional dynamic response, high resolution, and repeatable positioning accuracy in demanding motion control applications.

Engineering Features & Advantages
- Precision Performance: The nozzle-flapper pilot stage delivers extremely high resolution and low hysteresis, enabling accurate spool positioning and precise metering of hydraulic flow proportional to the command signal.
- Fast Dynamic Response: Optimized torque motor and pilot stage design provide high frequency response, making the valve ideal for closed-loop position, velocity, and force control systems requiring rapid actuation.
- Robust Two-Stage Architecture: The second-stage spool is hydraulically driven by the pilot stage, ensuring high flow capacity with minimal electrical input power and stable operation across the full pressure range.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve assemblies engineered for long service life and consistent performance.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original MOOG G761 series servo valve standards, ensuring drop-in replacement without system modification.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original MOOG standards, allowing straightforward retrofit into existing hydraulic systems without rework.
