Q: What symptoms indicate a faulty main pump proportional solenoid?
A: Common issues include weak digging force, unstable engine speed, fluctuating hydraulic pressure, slow work arm movement, excessive fuel consumption, or machine power drop under heavy load.
Q: How does this inverse proportional solenoid work?
A: The ECU sends electrical signals to the solenoid. It modulates hydraulic pressure inside the pump regulator to change pump displacement, automatically adjusting oil output according to working load to balance power and fuel usage.
Q: What should I confirm before ordering this solenoid valve?
A: Confirm your excavator brand, model and engine type, cross-check original part number, and verify pump regulator mounting structure to guarantee fitment.
