804009500 Hydraulic Brake Valve for XCMG GR165 Motor Grader

Product Overview

The 804009500 is an OEM-spec hydraulic brake control valve, purpose-built for XCMG GR series motor graders. As a key component of the grader hydraulic braking system, it regulates pressure for both service and parking brake circuits, delivering smooth, predictable stopping power for road construction, site grading and earthmoving work.

Core Functions

• Modulates output pressure from the hydraulic accumulator to brake actuators, for consistent brake feel and response

• Built-in pressure reducing and relief functions protect brake components from overpressure damage

• Maintains stable braking performance under different load weights and job site terrain conditions

Build & Quality

• Heavy cast iron housing resists impact and vibration, suited for harsh construction and mining environments

• Precision machined internal parts for accurate pressure control and long service life

• Every unit goes through full pressure calibration and leakage testing before dispatch

• Works reliably across -40°C to +120°C, compatible with standard mineral-based brake fluids

Installation & Fitment

Made to original equipment dimensions and performance standards, this valve is a direct drop-in replacement for the factory 804009500 brake valve. No extra modification is needed for installation. It fits both routine maintenance and full brake system overhaul jobs on XCMG motor graders.
