Moog D633-7381High-Pressure Direct-Acting Servo Valve

  • Product Introduction: A specialized direct-acting servo valve from Moog’s D633 series, designed to operate at extreme pressures while maintaining precise control. It is engineered for high-pressure hydraulic systems where traditional valves may fail, combining robust materials with advanced design to handle the stresses of high-pressure operation. The valve is suitable for industrial and aerospace applications requiring both high pressure and accuracy.

Detailed content

  • Technical Specifications: Maximum operating pressure is 500 bar (7250 psi), with a rated flow of 15 l/min (4.0 gpm) at 35 bar (500 psi) pressure drop. The valve uses a high-strength alloy steel body to withstand pressure stresses. Operating temperature range is -25°C to 120°C (-13°F to 248°F), accommodating high-temperature systems. Frequency response is ≥180 Hz, ensuring dynamic performance at high pressures.
  • Functional Features: Reinforced spool and sleeve materials resist wear and deformation under high pressure, extending service life. Precision lapped components minimize internal leakage, even at maximum pressure. The direct-acting design eliminates pilot stage limitations, ensuring consistent performance across the pressure range. Compatible with fire-resistant hydraulic fluids, suitable for high-risk environments.
  • Application Scenarios: Used in high-pressure test benches for validating hydraulic components, simulating extreme operating conditions. Integral to aerospace hydraulic systems, controlling actuators in aircraft landing gear and flight control surfaces operating at high pressures. Applied in industrial presses for compacting high-strength materials, where high pressure and precise force control are required.
