For Hyundais New R210LC-7 hydraulic Main Control Valve 31N6-1800

The working principle of the distributing valve:

   The engine flying rotation is connected with the elastic plate of the torque converter, the elastic plate is connected with the cover wheel, and the cover wheel is connected with the splitting teeth of the pump wheel, the rotating of the splitting teeth drives the working pump shaft gear to rotate, and the hydraulic working pump starts to work.
Excavator multi-way valve/distribution valve is mainly composed of the following valve blocks: electromagnetic directional valve, relief valve, check valve, throttle valve. The role of each valve block in the excavator multi-way valve/distribution valve is as follows: 1. The reversing valve: controls the oil inlet and outlet of the large arm and forearm cylinder, and the rotary motor walking motor inlet and outlet of oil
The main role of excavator multi-way valve

    Excavator multi-way valve/distribution valve is mainly composed of the following valve blocks: electromagnetic directional valve, relief valve, check valve, throttle valve.

The role of each valve block in the excavator multiway valve/distribution valve:

1, reversing valve: control the big arm, small arm cylinder in and out of oil, rotary motor walking motor in and out of oil, dodging oil cylinder in and out of oil.

2, relief valve: there are main relief valve and root relief valve, the main relief valve control system pressure, the root relief valve is related to the control mode of the system, positive and negative control.

3, check valve: control hydraulic oil flow in one direction.

4, throttle valve: control the flow of hydraulic oil.
