This PC60-7 hydraulic distributing valve perfectly matches all above construction sites, stable hydraulic flow distribution reduces equipment failure downtime for global mini excavator contractors, repair workshops & rental companies.

• Spool stuck: Hydraulic oil impurity blocks spool clearance, heavy operation handle, poor reset & insensitive boom/arm/bucket action
• Internal leakage: Worn gap between valve spool and valve body causes inner oil leak, leading to bucket drop and slow movement
• External oil leakage: Aging valve stem seal ring causes oil spill from valve body joint surface
• Unstable flow: Blocked spool leads to excavator jitter and uneven running speed
• Overflow valve failure: Stuck main relief valve or insufficient spring pressure, system no pressure or overpressure burst hydraulic pipe
• Cross-action interference: Damaged internal seal causes boom and arm action to interfere with each other

• Insufficient system pressure: Worn distribution plate, plunger or cylinder block causes internal leakage, whole machine slow & weak digging force
• Abnormal heat & vibration: Clogged oil suction filter leads to cavitation, metal collision noise and overhigh oil temperature
• Front oil seal aging causes hydraulic oil leak into engine compartment

• Weak swing & sliding slope: Severe wear of motor distribution plate, aging internal seal causes high-pressure internal leakage, machine can’t stop steadily on slope
• Swing jitter & abnormal noise: Broken reducer gear or damaged bearing produces metal friction sound during rotation
• Swing oil leakage: Damaged shaft oil seal leads to hydraulic oil spill from swing motor housing
• Swing stuck & high temperature: Long-time continuous slewing operation makes whole hydraulic system overheat

• Travel deviation: Inconsistent displacement of two-side travel motors, servo valve failure or central swivel joint seal oil leakage
• Single side no travel: Broken travel reducer gear or stuck parking brake can’t release normally
• Weak climbing travel: Stuck motor displacement adjustment mechanism, low speed with insufficient torque output

• Power drop & black smoke: Clogged air filter leads to insufficient air intake, poor atomization of fuel injector and high-pressure oil pump
• Overhigh water & oil temperature: Radiator blocked by silt, deteriorated engine oil or stuck thermostat
• Difficult startup: Starter failure, dead battery or air enters fuel pipeline
