Control Valve Assembly 527-6519 for Caterpillar Excavator 326GC,FM548, 330GC,Construction Machinery Aftermarket Parts manufacture

The main control valve for Caterpillar 326GC, FM548, 330GC excavator is primarily used to control the direction and pressure of hydraulic oil in the hydraulic system, enabling various movements of the excavator.

• Precise Action Control: Through solenoid valves and oil circuit design, it coordinately controls the movement speed and direction of devices such as the boom, arm, and bucket, enabling core excavation operations.
• System Pressure Protection: With the help of main safety valves and pipeline safety valves, it limits the maximum pressure of the system and local areas to prevent component damage due to overload.
• Anti-settling Guarantee: Equipped with boom and arm settling damping valves, it prevents accidental sinking of working devices caused by oil cylinder leakage, improving operational safety.
