German Made Moog Servo Valve with 25cm Nominal Diameter 280 Bar Maximum Pressure and -20°C to 80°C Operating Temperature

A MOOG Electro-Hydraulic Servo Valve is an electro-hydraulic conversion and power amplification 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.

• High-Precision Control: They offer exceptional control accuracy, which can reach about 0.1%, suitable for demanding applications.
• High Dynamic Performance: They feature fast response times, often in the millisecond range, allowing for high-speed and high-precision control.
• High Reliability and Stability: Designed with advanced technology and materials for stable long-term operation, even in harsh environments.
• Variety of Designs: Available in various series to meet different performance needs.
• Fail-Safe Functionality: Some models include a fail-safe feature that moves the valve to a safe position in case of a power failure or system fault.

MOOG offers a comprehensive range of servo valves including:

• G761 Series: Two-stage flow control valve with mechanical feedback
• D630 Series: Often feature direct drive by a linear force motor
• D660, D661, D662 Series: Classic two-stage servo valves
• 72 Series: Standard response two-stage 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
• Operating Temperature: -20°C to 80°C
