Excavator pilot control valve handle series

The excavator pilot control valve is a type of valve on the excavator operating rod, used to control various operating actions of the excavator.
The function of the excavator pilot handle valve is to control the flow and pressure in the hydraulic system based on the position and action of the operating handle, thereby controlling the actions of the excavator, such as excavation, shovel loading, and movement. Generally speaking, the excavator pilot handle valve has multiple positions and actions, which control the movement of hydraulic pumps, cylinders, and motors in the hydraulic system through operations such as lifting, pressing, and pushing rods.
