Product Overview
The MOOG G761-3003B / H19J0GM4VPL 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, double-nozzle pilot stage that hydraulically positions a four-way, closed-center spool in the second stage, delivering infinitely variable, bidirectional flow control proportional to the electrical input current. Engineered for closed-loop position, velocity, and force control architectures, the G761 series is the definitive component for applications demanding exceptional dynamic response, minimal hysteresis, and long-term null stability in continuous industrial service.

Engineering Features & Advantages
- Precision Performance: The torque-motor and double-nozzle pilot stage deliver extremely high resolution and repeatability, with low hysteresis and threshold, enabling accurate spool positioning and precise metering of flow for critical closed-loop motion control.
- High Dynamic Response: Optimized pilot-stage hydraulics provide fast spool actuation and high frequency response, making the G761-3003B ideal for demanding servo loops requiring rapid command tracking and disturbance rejection.
- Null Stability & Low Leakage: Closed-center spool design and precision-matched metering lands minimize internal leakage and maintain stable null offset over extended duty cycles, reducing thermal drift and improving system efficiency.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction, contamination-tolerant pilot filtration, and proven MOOG manufacturing quality for long service life.
- Direct Fit Replacement: Precision-manufactured to original MOOG specifications for direct replacement, minimising downtime and eliminating fitment issues.
