Frequently Asked Questions
Common Failure Modes and Troubleshooting
  • Valve does not respond/no movement:
    Cause: No electrical signal, coil failure, or severely stuck spool.
    Action: Check input signal and power supply. Verify coil resistance with a multimeter. Inspect for spool stuck due to oil contamination.
  • Erratic or unstable operation:
    Cause: Contamination blocking the spool or orifices, worn spool, or feedback sensor issues.
    Action: Check oil cleanliness and filters. Clean valve internals. Verify signal integrity.
  • Increased leakage or unable to maintain pressure:
    Cause: Internal wear of the spool and sleeve or damaged seals.
    Action: Check for wear. Replace valve or seals as necessary.
  • Slow response:
    Cause: Air in system, clogged damping orifices, or failing solenoid.
    Action: Bleed air from system. Clean valve thoroughly.
Calibration Frequency
  • General guideline: Annual calibration for normal conditions
  • High-precision/harsh appliions: Every six months or quarterly
  • After repair/modifiion: Always calibrate before returning to service
Repair and Calibration Process

Simple mechanical issues can often be resolved through disassembly and cleaning by trained technicians. Calibration requires a dedied test bench to adjust mechanical and electrical zero positions, and should be performed by qualified personnel.
