Case Excavator Solenoid Valve KHJ15450

KHJ15450 is a 4-spool solenoid valve group (24V DC) used for pilot pressure control on Sumitomo and CASE excavators. On Sumitomo machines, it corresponds to fault codes 7200 (Swing Brake Solenoid), 7201 (Travel Speed Solenoid), and 7202 (Boost Solenoid). Fault symptoms

primarily manifest as reduced hydraulic power, engine over revving, warning lamp illumination, and potential mode. Diagnosis focuses on coil resistance measurement (18–25 ohms), voltage supply verification (12–24V DC), and harness inspection.
