Summary of Product

The main control valve is a core hydraulic component having a large influence on the performance, work efficiency and fuel efficiency of an excavator and is composed of very complicated internal hydraulic circuits for functioning to accurately control the operation of a hydraulic drive device, such as a pump, a motor, a cylinder and the like. Furthermore, the main control valve is core hydraulic equipment required to have high size accuracy and rigidity against high pressure because a high pressure of 350 bar or more is operated.
