The main control valve (multi-way valve) is a complex component of the excavator hydraulic system. It distributes the hydraulic power of the hydraulic pump to the upper arm and lower arm bucket cylinder to perform the action, to the rotary motor and the walking motor, and to perform the rotation and forward and backward walking. The feedback signal controls the output power of the hydraulic pump to suit the load. Feedback to the engine idle automatically, saving fuel. When combined action, let the rotation take precedence and the river of forearm improve the function of smooth and safe movement. Multiplex valves are mainly original assemblies, and the original pure parts sells very little in the market.
