FAQ:
What are the key features?
• High precision: Control accuracy up to ~0.1% .
• Fast dynamic response: Responds within milliseconds .
• Programmability: Customizable control algorithms via embedded electronics .
• Robustness: Operates in harsh environments (-20°C to 80°C) and resists contamination .
• Fail-safe function: Automatic shutdown during power loss or failure .
3. What are common failure modes?
• Torque motor issues:
◦ Coil breakage (valve fails to respond) .
◦ Armature sticking or ball head wear (causing instability) .
• Nozzle/flapper blockages: Clogging from oil contamination reduces response and causes system oscillation .
• Spool amplifier problems:
◦ Edge wear (increases leakage and noise) .
◦ Spool sticking due to contaminated or degraded oil .
• Seal aging: Leads to internal/external leakage .
4. How to maintain servo valves?
• Oil quality management: Use recommended fluids (e.g., phosphate ester fire-resistant oil) and maintain cleanliness per NAS 1638 Class 5 standards. Regularly check acidity and resistivity .
• Routine inspections: Test for electrical issues (e.g., coil resistance), clean filters, and check for loose components .
• Pre-startup checks: Ensure oil circulation before powering the valve to prevent clogging .
5. How to troubleshoot unstable operation (e.g., cylinder drift or oscillation)?
• Check servo valve resolution and zero zone stability .
• Inspect for internal leakage or spool wear .
• Verify control system parameters and calibrate zero bias if needed .
6. What if the valve doesn’t move?
• Confirm electrical signals and coil connectivity .
• Check for spool sticking caused by debris in oil .
• Ensure correct startup sequence: oil flow before electrical power .
7. Can Moog servo valves be customized?
Yes. Models like the D636/D637 series support fieldbus interfaces and programmable electronics for application-specific tuning .
8. What specifications should I consider?
• Operating pressure: Up to 350 bar .
• Flow rate: 5–100 L/min (at Δp 35 bar) .
• Voltage/current: Typically 220V, 1.5A .
• Mounting: Complies with ISO 4401 standards .
9. How to ensure long-term reliability?
• Use high-quality filters and maintain oil cleanliness .
• Avoid prolonged operation beyond rated temperatures .
• Schedule periodic professional servicing .
10. Where are Moog servo valves used?
Applications include aviation, aerospace, steel mills, power generation, and industrial automation .
For specific model details (e.g., G761-3004B or D661 series), refer to technical datasheets or contact authorized suppliers .
