Excavator Komatsu PC200-7K, PC240-7K PC210-7K main control valve or multi-way valve 723-48-22700 723-48-23600

Multi-way valve components 723-48-22700 and 723-48-23600 designed for Komatsu PC series excavators, providing precise hydraulic control for optimal machine performance.

• Slow and weak machine movements
• Weak operation of single actuator (boom / arm / bucket / swing / travel)
• Jerky and vibrating movement
• Interference during combined operation, poor flow merging
• External leakage of main control valve, oil seepage and oil leakage on valve body
• Severe internal leakage, rapid pressure drop and poor pressure retention
• Spool sticking, no response of corresponding function
• Worn overload relief valve, low system pressure
• Damaged check valve, abnormal return of operation
• Scuffed valve bore, continuously increasing internal leakage
• Unstable pilot control pressure, erratic movement speed
• Aging and failure of seals, multiple oil leaks
