Hitachi excavator accessory 9239590 proportional solenoid valve (single valve)

This product is a proportional solenoid valve in the hydraulic system of Hitachi ZX-3 series excavators, which is a core control component of the main pump regulator or related control circuits. By receiving electronic control signals and accurately adjusting the pilot oil pressure, the proportional control of the main pump flow and pressure is achieved, thereby completing functions such as power boost, regeneration circuit, and high-low speed switching, ensuring smooth, efficient, and energy-saving machine operation.
