Key Features
  • Constant Power Variable Control: Built-in hydraulic power regulator automatically adjusts flow output according to digging load, preventing engine speed drop and stalling during heavy-duty work.
  • Dual Pump Combined Flow: Integrated dual piston pump design provides high oil delivery for simultaneous boom, arm, swing, and travel operations without oil competition.
  • High Precision Components: Precision ground cylinder block, piston, and valve plate offer excellent performance under high temperatures and poor hydraulic oil conditions.
  • Stable Pressure Output: Strictly controlled internal leakage maintains consistent performance between cold and hot operating conditions.
  • Direct OEM Replacement: 1:1 mounting dimensions with identical flange, oil port, and spline sizes for easy installation without modifications.
