Product Overview
The MOOG G761-3008B is a high-performance, two-stage electrohydraulic servo valve manufactured by MOOG, the global benchmark in precision motion control. It operates on a nozzle-flapper pilot stage (first stage) that hydraulically deflects a spool within the second-stage sliding spool assembly, delivering infinitely variable, bidirectional flow control proportional to the electrical input current. Designed for closed-loop position, velocity, force, and pressure control, the G761-3008B serves as the critical interface between electronic command signals and high-pressure hydraulic actuation in demanding industrial and aerospace-grade motion systems. Its dry torque motor, rugged spool-in-bushing design, and field-proven mechanical feedback architecture ensure fast dynamic response, minimal hysteresis, and long-term null stability.

Engineering Features & Advantages
- Precision Performance: The nozzle-flapper pilot stage delivers extremely high resolution and low threshold, enabling accurate micro-positioning and smooth velocity control in closed-loop servo systems.
- Fast Dynamic Response: High spool drive force and low inertial mass yield rapid step response and wide frequency bandwidth, essential for high-cycle industrial motion profiles.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a dry torque motor isolated from hydraulic fluid and a hardened, wear-resistant spool-in-bushing assembly for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original MOOG G761 series OEM standards, ensuring drop-in interchangeability without subplate or piping modification.
Typical Industrial Applications
The MOOG G761-3008B is deployed across heavy industrial and high-precision motion control scenarios, including plastic injection molding machines requiring precise injection and clamp force control, metallurgical presses and rolling mill gauge control
