804000807 XCMG GR2605 motor grader pressure reducing valve assembly

804000807 XCMG GR2605 motor grader pressure reducing valve assembly

Core Product Advantages

Specifically designed and developed for the XCMG GR2605 motor grader, this product perfectly matches the model’s 194kW power output and 22MPa working pressure requirements, ensuring stable reliability in harsh working conditions such as mining and infrastructure projects. Utilizing a pilot-operated control structure, combined with wear-resistant sealing materials and a precision valve core design, it achieves millisecond-level pressure response, effectively buffering pressure fluctuations and preventing damage to the hydraulic motor and actuators due to overpressure, thus extending the overall machine’s service life. The integrated design simplifies the installation process, eliminating the need for additional electrical control devices; pressure reduction and stabilization are achieved solely through the pressure of the medium itself, reducing maintenance costs and energy consumption.
