G761-3600B Moog Electro-Hydraulic Servo Valve

Product Description: G761-3600B is a two-stage mechanical feedback electro-hydraulic servo valve from Moog G761 series, adopting nozzle-flapper pilot stage structure. It converts analog current control signals into precise hydraulic flow output, realizes high dynamic closed-loop control of pressure, position and speed. It is a classic high-precision motion control component, widely used in turbine, test bench and simulation equipment, and belongs to legacy critical spare parts for hydraulic control systems.

Features

• Nozzle-flapper two-stage design with mechanical feedback, low hysteresis and ultra-high resolution
• Fast dynamic response, short step response time for high-frequency control loops
• Max working pressure up to 315 bar, standard 4-port hydraulic interface
• Analog current command input, dual coil configuration, support series or parallel wiring
• Precision spool and sleeve matching, stable performance under continuous working conditions
• Compact structure, strong anti-interference for closed-loop hydraulic control
• End-of-life for new projects, available for stock supply and professional repair service

Application Scenarios

• Steam & gas turbine governor hydraulic control system
• Aerospace and material fatigue test bench
• Motion simulation platform and shaking table equipment
• Steel mill rolling mill hydraulic servo control
• Offshore and heavy industry precision hydraulic control loop

FAQ

Q: What is the working principle of G761-3600B?
A: It receives current control signal, drives the nozzle-flapper pilot stage, then controls the main spool to output hydraulic flow for closed-loop motion regulation.

Q: Is this servo valve suitable for new project design?
A: It is a legacy model, Moog does not recommend it for new designs; it is mainly used for existing equipment replacement and maintenance.

Q: What signal type does it accept?
A: It is controlled by differential analog current signal, the common command signal is ±15mA.

Q: Can it be repaired after failure?
A: Yes, professional overhaul, cleaning, calibration and performance testing services are available for this series servo valve.
