LIUGONG 12C5771 Wheel Loader Pilot Oil Supply Valve Assembly

● LIUGONG 12C5771 Valve Technical Support

● Part number 12C5771 is the genuine hydraulic pilot oil supply valve assembly engineered for LIUGONG H-series wheel loaders.

● Material number 12C5771 is mounted within the front chassis hydraulic control manifold bay, connecting primary high-pressure fluid lines to the pilot accumulator and operator cab joystick controllers. It steps down system pressure to maintain a steady, regulated pilot oil flow, ensuring responsive, smooth proportional actuation of main lift and tilt spool valves during loading and dumping cycles.

● Regularly inspect internal pilot pressure relief settings, accumulator pre-charge pressure, and hydraulic line seal integrity during scheduled maintenance to prevent control lag or jerky hydraulic movement.
