Flow control valve troubleshooting
1. Throttle valve failure
Flow regulation failure: Check whether the valve core is stuck and whether the throttle is blocked. Clean the spool and throttle.
Leaks: Check the seals and replace the damaged ones.
2. The speed control valve is faulty
Unstable speed: It may be that the gap between the spool and the valve sleeve is too large, the spool spring of the pressure reducing valve is failing, etc. Parts need to be repaired or replaced.
Directional control valve troubleshooting
1. Check valve failure
Reverse Leak: Check the seal, replace the damaged one.
No one-way action: the spool is stuck by impurities or the spring is damaged, clean the spool or replace the spring.
2. Failure of the reversing valve
Non-reversing: Check whether the solenoid is damaged, whether the valve core is stuck, and whether the control oil circuit is blocked. Repair or replace the solenoid, clean the spool and control oil circuit.
Inadequate reversing: Adjust the spool stroke or check if the spring is suitable.
