3. Common Reducing Valve Block Failure Troubleshooting
- Fault 1: Excavator Joystick Operation Becomes Stiff & Heavy
Cause: Internal spool wear, spring fatigue, dirt impurity trapped inside valve clearance.
Solution: Install brand‑new 6723‑40‑70100 Reducing Valve Block, flush hydraulic circuit and replace hydraulic filter. - Fault 2: Pilot Pressure Unstable, Machine Action Intermittent
Cause: Valve core abrasion, internal spring performance degradation.
Solution: Fit PC200 6723‑40‑70100 Reducing Valve Block, thoroughly clean whole hydraulic oil loop. - Fault 3: Hydraulic System Produces Abnormal Noise & Heat
Cause: Internal component wear, oil passages blocked by hydraulic contamination.
Solution: Replace complete reducing valve block assembly, inspect hydraulic oil cleanliness status. - Fault 4: Oil Leakage On Reducing Valve Block Mounting Surface
Cause: Seal ring aging, mating surface scratch damage.
Solution: Change full reducing valve block assembly or matching seal repair kit.
