Maintenance Guidelines

  1. Regular Inspection: Periodically check electrical connections and mounting bolts for tightness.
  2. Keep Dry & Clean: Protect the solenoid coil from moisture, dust, and hydraulic fluid contamination.
  3. Voltage Verification: Ensure the supplied voltage matches the rated 24V DC to prevent coil burnout or insufficient force.
  4. Stroke Monitoring: Monitor actuation stroke over time; excessive wear may indicate internal contamination or mechanical fatigue.

Safety Precautions

  • Always disconnect power before performing installation or maintenance.
  • Do not exceed the maximum rated oil pressure (21 MPa) to avoid component failure.
  • Ensure proper grounding of the hydraulic system to prevent electrical hazards.
  • Operate within specified temperature and humidity ranges as per standard industrial guidelines.

Frequently Asked Questions

Can this solenoid be used with AC power supplies?
No, the MFZ12-37 (PK) is specifically designed for DC circuits (typically from a rectified AC source). Using direct AC power will damage the coil.
What is the maximum operating pressure?
The solenoid is rated for a maximum oil pressure of 21 MPa. Exceeding this limit may compromise valve sealing and solenoid lifespan.
Is it compatible with other valve sizes besides NG6 and NG10?
This model is optimized for NG6 and NG10 screw-connected directional valves. For other sizes, please consult our engineering team for suitable alternatives.
