MOOG Electro-Hydraulic Servo Valve
Frequently Asked Questions
1. What is a MOOG Electro-Hydraulic Servo Valve and how does it work?

A MOOG Electro-Hydraulic Servo Valve is an electro-hydraulic conversion and power amplifiion component. Its primary function is to receive analog electrical control signals and then proportionally adjust the output flow and pressure of hydraulic fluid based on these signals, thereby achieving precise control of hydraulic actuators.

2. What are the main advantages of MOOG Servo Valves?
  • High-Precision Control: They offer exceptional control accuracy, which can reach about 0.1%
  • High Dynamic Performance: They feature fast response times, often in the millisecond range
  • High Reliability and Stability: Designed with advanced technology and materials for stable long-term operation
  • Variety of Designs: Available in various series to meet different performance needs
  • Fail-Safe Functionality: Some models include a fail-safe feature
3. What are the main series of MOOG Servo Valves?
Series Key Characteristics Typical Appliions
G761 Series Two-stage, mechanical feedback, high response Industrial machinery
D630 Series Direct drive by a linear force motor (DDV) Precision control systems
D660, D661, D662 Series Classic two-stage servo valves Wide range of industrial uses
72 Series Standard response two-stage valves Power generation
4. What are the typical operating parameters for MOOG Servo Valves?
  • Maximum Operating Pressure: Up to 4000-4500 psi (approx. 31.5 MPa)
  • Flow Control Range: From a few liters/minute to very high flows
  • Input Signal: Typically a current signal (e.g., ±40 mA) or a voltage signal
  • Coil Resistance: Typically in the range of 72-88 Ω
  • Operating Temperature: -20°C to 80°C
5. Where are MOOG Servo Valves commonly used?
  • Industrial Machinery: Metal forming equipment, wood presses, plastic machinery
  • Power Generation: Control of steam turbine valves, gas turbine fuel systems
  • Test and Simulation: Automotive and aerospace test rigs, flight simulators
  • Other Fields: Robotics, material handling
6. What are the most common failures and how can they be diagnosed?
Common failures:
  • Torque Motor Issues: Broken coils, contamination in air gap, loose fasteners
  • Nozzle/Flapper Stage Issues: Clogged nozzles or orifices
  • Spool Amplifier Stage Issues: Spool sticking, cutting edge wear
System-level symptoms:
  • Cylinder Refusal to Move: Often due to a stuck servo valve
  • Uncontrolled Valve Movement: Sudden full opening/closing
  • Cylinder Oscillation ("Cylinder Hunting")
  • High Cylinder Lag
