31N5-16111 Hydraulic Main Control Valve for Hyundai R160LC-7A R180LC-7A Excavator

The hydraulic main control valve 31N5-16111 is primarily used to distribute the pressure oil discharged by the pump to various actuators according to the operator's instructions, enabling the excavator to perform actions such as digging, lifting, rotating and traveling.

Its core functions include:

• Precise Hydraulic Oil Distribution - According to the operator's instructions, it directionally distributes the pressure oil output by the pump to each actuator of the excavator, while regulating the flow direction and flow rate of the oil to provide basic power support for action execution.
• Driving Multi-Action Execution - Through oil distribution and flow control, it realizes the core operating actions of the excavator such as digging, lifting, rotating and traveling, ensuring precise response and smooth operation of each action.
• Ensuring Stable System Operation - Integrating the functions of relief valves, unloading valves, holding valves and other valve groups, it balances the pressure of the hydraulic system, prevents abnormal situations such as overload and leakage, and ensures the overall stability of the hydraulic system and reliable operation of the equipment.
