Product Overview
The MOOG G761-3008B / H19J0GM4VPH is a high-performance, two-stage electrohydraulic servo valve engineered by Moog Inc., the global benchmark in precision motion control. This valve operates on a torque-motor pilot stage driving a spool-type second stage, delivering infinitely variable flow control proportional to an electrical input current. As a critical control element in closed-loop hydraulic systems, it translates low-power electrical command signals into precise, high-response hydraulic output, enabling exact position, velocity, and force regulation in demanding industrial and aerospace-grade applications.

Engineering Features & Advantages
- Precision Metering: The torque-motor pilot stage provides extremely fine resolution and low hysteresis, ensuring accurate spool positioning and repeatable flow output proportional to input current.
- High Dynamic Response: Optimized nozzle-flapper design delivers fast step response and high frequency bandwidth, essential for closed-loop control of high-performance actuators.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened spool and sleeve for long service life and minimal internal leakage.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM Moog G761 series servo valves, ensuring drop-in interchangeability without system modification.
Typical Industrial Applications
This servo valve is widely deployed in high-precision motion control systems, including plastic injection molding machines requiring exact injection velocity and pressure profiling, metallurgical presses for accurate force and position regulation, CNC machine tools and robotics for multi-axis interpolation, and test rigs for fatigue and structural testing where dynamic response and repeatability are critical. It is also found in power generation turbine control and marine stabilizer systems demanding robust, continuous-duty hydraulic modulation.
